is advised. This is episode fortyeight, the murder of Sharon Siermans.
Four year old Aaron Siemans looked upat his paternal grandmother Ann and said,

(01:04):
mummy's up there. The uneasy feelingin Anne's stomach grew, knowing that her
daughter Sharon would never leave Aaron unsupervised. Anne had gone to the house that
the mother and son shared on DuftonStreet in Ballarat, Victoria, Australia,
after Sharon had failed to turn upfor a prearranged meeting on April six,

(01:25):
twenty thirteen. Aaron turned to hergrandson once more, asking him to clarify.
As she surveyed the house, shenoticed a trail of blood on the
floor and calmly asked Aaron what hadhappened. Much to Anne's horror. Aaron
replied, quote, there was abig man coming last night and he bashed
mummy with a baseball bat. Mummywon't wake up and give me any breakfast

(01:48):
end quote. The uneasy feeling inAnne's stomach grew. She ran outside to
her boyfriend, who was waiting inthe car, and asked him to go
and check on Sharon. Unable todo her through fear of what she might
find. Her gut instinct was right, and as Ann's boyfriend entered Sharon's bedroom,
he would come across a site thatwould change the lives of the Siemens

(02:10):
family forever. Sharon lay dead inher bed after suffering blunt force trauma to
the head at the hands of aman she had met just once. The
man who murdered her was a knownrapist, abuser, and criminal, yet
he was able to slip through thecracks and was given a parole period following
a horrific strings of assaults and rapeson women. When Sharon opened up the

(02:35):
Plenty of Fish app she had noidea of the nightmare that she was walking
into. Twenty nine year old SharonSiemans was a dedicated mother to her son
Aaron Sharon had met Aaron's father,who has not been publicly named, whilst
working for a commercial cleaning company.The two hit off right away and they
quickly became an item. Sharon fellpregnant, the two moved in together,

(03:00):
hoping to create a safe and stablehome for their child. After three years,
the relationship broke down, with Aaron'sfather moving out, leaving just the
two of them. Sharon was determinedto make the best of a bad situation
and through everything that she had intocreating a stable and happy life for a
son who was her world. Shetook a nail technician course and opened up

(03:23):
a nail bar from the comfort ofher own home. This job gave her
the flexibility and independence that she neededto raise her young son. She could
set her own hours, and withthe nailbar being at home, she was
always there for Aaron when he neededher. Sharon and Aaron were living at
a rented property on Duveton Street inBallarat from a family friend. Sharon had

(03:46):
grown up in Ballarat and was familiarwith the area and knew that she would
be able to safely raise her sonthere and make a good life for herself.
One article notes that Sharon had amild intellectual disability. However, the
scope of this is never discussed further. Despite all of the obstacles in a
way, Sharon did everything she couldto make life great for Aaron, and

(04:11):
those around her always spoke very,very highly of her. A few years
after the relationship with Aaron's father hadbroken down, Sharon decided it was time
to get back out there and meetsomeone new. Sadly, for Sharon,
she would cross paths with the wrongman, a man who was known to
Australian law enforcement and a man whoshould have never been allowed to roam the

(04:33):
streets. In early January thirteen,Sharon browsed through the various dating apps available
and downloaded the popular app Plenty ofFish. After creating a profile, she
sifted through hundreds of profiles, gettinga field for people in her area.
As she was swiping through profiles,one caught her attention, in particular,

(04:58):
thirty eight year old Jason and JohnDinsley. The two matched and began chatting
on the app, and they exchangedphone numbers and agreed to chat that way
after getting to know each other alittle bit better. By all accounts,
the conversation between the two was great. They texted back and forth, and
once they'd become more comfortable with eachother and gotten to know in each other

(05:21):
a little bit better, they decidedthat it was finally time to meet in
person for a first date. Throughhis series of texts, Jason put Sharon
at ease, sending hearts and floweremojis and exuding positive energy. She had
no fears about meeting him in personand wondered whether this could be the start

(05:42):
of something wonderful. On January nineteenth, thirteen, Jason and Sharon met at
the Ballarat train station. As pertheir agreement. The plan was for the
two to head over to a localrestaurant and get each other a little bit
better over a meal, but whenJason stepped out of the train station,

(06:04):
Sharon realized that he was nothing likehis profile. She told friends that she
felt sorry for him in a wayand that he was smelling and dirty.
Not wanting to be seen with himin public because she was embarrassed, Sharon
invited him back to her house fora coffee. The two chatted over coffee

(06:24):
and Sharon did her best to makepolite, casual conversation. As the date
progressed, Sharon became more and moreuncomfortable in Jason's presence, so much so
that she texted a close friend andhas her to fake in emergencies so that
she had an excuse to get awayfrom Jason without seeming rude or abrupt.

(06:45):
Following the phone call, Sharon droveJason back to Ballarat train station and breathed
a sigh of relief. She hadfinally gotten rid of him. Also,
she thought Jason did not handle thisrejection well. Instead of accepting the fact
that Sharon didn't want to see himanymore, he began harassing her and sending

(07:08):
her death threats. Sharon tried toget on with her life and kept these
threats a secret from her friends andfamily, probably in the hopes that if
she ignored him, he would eventuallyget born and go away. Between January
and April of two and thirteen,Jason's anger grew and culminated and resulted in

(07:31):
one of Australia's most evil crimes.For months, he sat and planned how
he could take his revenge on Sharon, and in April six, twenty thirteen,
that is exactly what he did.According to Jason, On the evening

(07:51):
of April six, two thirteen,He was out on a walk at around
two am when he passed Sharon's houseon Dobton Street. Walking past Sharon's house
awoke something inside of him, andhis rage just boiled over. Instead of
continuing with his walk, Jason madethe one point six mile journey home to

(08:13):
retrieve a weapon. As he enteredhis home, he found a cricket bat,
swung it into his hands and knewthat that was exactly what he needed.
After retrieving the weapon, he walkedanother one point six miles back to
Sharon's house on Dufton Street and beganhis brutal tirade. Jason broke into Sharon's

(08:37):
home by removing glass panels and climbingin through a window. This noise,
of course, woke Sharon up,and she rushed to see what was going
on, only to find Jason crawlingthrough a window. Sharon confronted him,
asking him what the hell he wasdoing in her house, but before she
had time to defend herself or doanything, he swung and hit her over

(09:01):
the head with the cricket bat thathe had retrieved from his home. The
blow knocked her to the floor,and Sharon desperately held her hands up,
trying to defend herself and make thebeating stop, but Jason continued swinging.
Her screams woke up her four yearold son, Aaron, and Jason told

(09:22):
her that she should check on him. Once Sharon had consoled Aaron, who
would witness some of the attack,it is believed she was forced back into
her own bedroom where it was justher and Jason. Most of this information
comes from the coroner's report, andaccording to this report, Jason tried to
rape Sharon but was unable to getan erection, so in his rage field

(09:46):
state, he picked up the cricketbat once more and began swinging. When
later asked by police how many timeshe had hit Sharon, Jason said that
he didn't know, but he saidthe only was I didn't stop. Sharon
fought until the very end, butJason overpowered her and killed her. Once

(10:07):
he had finished, he stole herphone and left the house as if nothing
had ever happened. Sharon's body wasdiscovered the next morning by her mother's boyfriend
after she had failed to show upfor a pre arranged meeting. This discovery
rock Sharon's family, and within minutesthe police had arrived at the scene and

(10:30):
opened their investigation. Forensic pathologist doctorMelissa Baker of the Victorian Institute of Forensic
Medicine determined that Sharon's cause of deathwas blunt head injuries and that quote Miss
Simmons was noted to have an incisedinjury to the neck and multiple bruises over
her left shoulder and right and leftlimbs. Some of the bruises were consistent

(10:52):
with defense injuries end quote. Thereport also stated that quote doctor Baker noted
that the force required to cause thehead injuries was extreme and that the head
injuries would have been rapidly fatal endquote. The Victoria police began searching through
Sharon's phone and social media and cameacross the various messages between herself and Jason

(11:18):
Dinsley. Jason was brought in forquestioning, where he pretty much admitted to
everything. As a result, hewas charged with murder, attempted rape,
and aggravated burglary. He was placedin front of a court for his preliminary
hearing, where he played guilty onall three charges, which spared Sharon's family

(11:39):
the trauma of going to trial.At his sentence in in December twenty thirteen,
Jason Dinsley was sentenced to life inprison with a non parole period of
at least thirty two years. Atthe hearing, Justin Hollingworth addressed Jason,
saying, quote, murder is themost serious effect known to our legal system

(12:01):
and our community, and this isan extremely serious example of that offense.
Using a weapon which you were broughtwith you for the purpose of frightening or
harming Missus Siemens, you engaged ina sustained, ferocious and cowardly attack on
an unarmed, defenseless woman in herown home in the middle of the night.

(12:22):
You may not have seen Aaron onthe night, but you were aware
that Missus Siemens had a young childwho lived with her. You were recklessly
indifferent to whether or whether or nothe witnessed what he did to his mother
or found her body afterwards. Endquote. During the sentence in hearing,
details of Jason's prior convictions were releasedand the public were shot to find that

(12:45):
he had over one hundred and fortyconvictions to his name. In two thousand
and two, he was found guiltyof serious injury and unlawful assault. Then
in two thousand and six, hewas arrested and charged with two counts of
rape, aggravated burglary, false imprisonment, intentionally called an injury, robbery,

(13:05):
and obtaining financial advantage by deception fora horrific crime that he committed against a
woman in a Saint killed a hotelin two thousand and five. For his
disgusting, horrific crimes, Jason wassentenced to just nine years in prison with
a non parole period of six anda half. By the time that twenty

(13:26):
twelve were rolled around, he hadbeen released after serving seven years of his
nine year prison sentence and was stillon parole when he murdered Sharon. According
to the coroner's report into Sharon's death, Jason was risk assessed shortly before his
release of prison, with the reportsaying quote the initial assessment indicated Dinsley had

(13:48):
a moderate risk of general reoffending.However, this was manually overridden by senior
staff to record a high risk ofreoffending end quote. Jason had also been
taking part in rehabilitation programs during histime in prison, and the report from

(14:09):
this reads quote His participation in thisprogram was described as satisfactory. A report
from Sex Offenders programs stated that Dinseley'sparticipation in MMIOP, which is Modular Management
and Intervention program, said that hedeveloped an increased level of insight into his
offending and some limited risk management strategies. However, those strategies had not been

(14:35):
tested in the community. Accordingly,it was suggested that Dinsley would benefit from
continued psychological support whilst on parole endquote. In twenty eleven, a year
before he was paroled, those incharge of Dinley's assessments quote, recommended Dinsley
not be released on parole as hedidn't have suitable accommodation, and it was

(14:58):
recommended that the APB request a furtherparole plan. The parole assessment summary noted
that his extensive criminal past and druguse, and that he was at high
risk of reoffending end quote. Itappears that all of these warning signs were
ignored, and just a year later, Jason was released on parole and ordered

(15:18):
to report just twice a week.In February twenty thirteen, his parole officer
noticed that he had began slipping oncemore, but nothing was done about this.
He had failed a drug test anda report was submit in detail.
In his rapid decline. The Paroleoffice was told that they should get Jason

(15:43):
to quote show cause as to whyhe should remain within the community, and
this meeting was set to take placeon April eighth, two thirteen. By
April eighth, three thirteen, itwas already too late. Sharon Siemens had
been dead for two days. TheAustralian parole system and prison system and justice

(16:04):
system showed systematic failings in its approachto Jason Dinsley and its regard for keeping
women safe. Dinsey was allowed tobe paroled despite knowing that he was a
serious offender with prior convictions for harmagainst women, and that he was at
a high risk of re offending.Sharon Simmons had no idea that she had

(16:26):
matched with a volatile criminal on plentyof fish. If Dinsley had been more
closely monitored and probably never paroled inthe first place, Sharon's life could have
been spared and Aaron wouldn't have hadto have grown up without his mother.
