Patterson now she's been foundguilty.
She said quote because she'sbeen found guilty.
She's been taken from hercustody box in the court through

(03:17):
what we believe is a lift intoa tunnel that connects to the
police station.
She said quote She'll be put inthat prison van and she'll
travel to Dame Phyllis Frost.
That's a maximum securitywomen's prison in Melbourne
they're my words, not hers andthere we are unlikely to see her
again until about August.

(03:38):
That's when her next courthearing has been scheduled.
Now she will presumably stay inDame Phyllis Frost until the

to life in prison house.

incredible thing on the HeraldSun, and I'm going to share it
with you.

(04:53):
Dowsley, and it says hold on toyour seat, get ready.

prison food.
Now this came out today, the7th of July, and it says triple
murderer Erin Patterson wasaccused of tampering with prison
food that made another inmatesick while waiting for her

(05:17):
high-profile trial to begin.
The allegation was made by afellow inmate who was held in
the same unit as Patterson at amaximum security prison,
danefellis Frost Centre inMelbourne.
Patterson was thrown behind barsin November 2023 and was
charged with murdering herestranged husband's family.

(05:37):
So we know those bits.
Sources said the mushroom cookhad fallen out with other
inmates last year before atleast one prisoner fell sick
when they ate a meal that wasprepared in the unit.
Oh my God.
The mother of two was thentransferred into a hard lockdown

(05:58):
area known as the slot.
While officers probed the claimin the slot, inmates were
placed in solitary confinementfor more than 22 hours a day
with little human contact.
It's understood.
The complaint about Pattersonwas investigated, but no known
further action was taken.
Patterson's camp said theallegation was baseless.

(06:22):
The Herald Sun was preventedfrom reporting the alleged
incident when she was awaitingher trial interesting, isn't it?
But she denies it.
The article goes on to sayanother source said patterson
had acted completely entitledwhile she was on remand at dame
phyllis frost center quote allthe girls have issues with each

(06:45):
other in there.
This person said the unit Erinwas housed in was almost like a
melting pot of tension, as theyare confined to the middle of
the jail and have to be escortedanywhere they go.
