True Crime

12:23 PM PT -- Christine Russo joined us today on "TMZ Live" Wednesday, where she explained that Mackenzie's behavior is making a mockery out of their family's tragedy.

Mackenzie Shirilla is posting glammed-up prison selfies on Instagram ... but Dominic Russo's sister tells TMZ all she sees is a convicted killer soaking up attention online.

Mackenzie's new prison selfie and a message saying she's "trying to do better every day and holding on to hope" has Christine Russo demanding prison officials investigate whether she's improperly accessing social media behind bars.

Christine tells TMZ ... "As Dominic Russo's sister, it is heartbreaking to see someone convicted in connection with my brother's death appear to have a social media presence while our family is suffering every day. While my brother is buried, seeing her post selfies, full face of makeup, and bragging how she is famous is painful and, to me, completely inconsistent with remorse."

Taylor Parker's disciplinary file behind bars appears to be remarkably thin ... and the lone conduct report is over her chosen sleeping arrangement ... TMZ has learned.

According to jail records obtained by TMZ, Parker was written up after allegedly refusing a direct order from a correctional officer.

The incident report says the official ordered Parker to stop sleeping on the floor using her mattress ... however, according to the write-up, Parker "failed to obey the order."

Mackenzie Shirilla is sharing a new photo from behind bars ... along with a positive message after suffering a legal setback.

Despite being locked up, Mackenzie's supporters are using her Instagram account. In a recent post, they uploaded a snap of her from prison, explaining she's "trying to do better every day and holding on to hope" ... despite a recent court decision denying her request for post-conviction relief.

Mackenzie's team explained the denial wasn't based on the substance of her claims. Instead, they said the filing was rejected because it was submitted one day past the deadline.

Taylor Parker told investigators her pal Reagan Simmons-Hancock was screaming at her to "take her out of me" while she was performing a makeshift C-section ... while being questioned about Reagan's murder.

TMZ obtained video of the interrogation from a Bowie County court -- taken just days after Reagan's murder in 2020 -- where Taylor describes her version of the grizzly scene, saying she only remembers hitting Reagan in the head with a mason jar before eventually performing the C-section ... at what she claims her victim's dire request.

Taylor says she told Reagan she didn't know how to get to the baby ... with Reagan's only response being, "Get her out of me!" after the two women went at it, shoving each other around, according to Taylor's side of the story.

Taylor Parker sobbed and insisted she's "a good person" ... as she's being interrogated for murdering Reagan Simmons-Hancock and stealing her unborn daughter, Braxlynn, from her uterus.

In interrogation video obtained by TMZ -- from just days after Raegan's murder -- Taylor cried to cops, saying she will "never understand it."

Investigators got Taylor to walk them through the night before the murder ... she says Raegan knew wasn't actually pregnant and was helping her figure out how to prevent her boyfriend, Wade Griffin, from catching her in the lie.

The body of suspected murderer Daniel Robbins was found in a ditch in a remote forest in Alabama ... and his alleged victim's corpse was lying right beside him.

Robbins allegedly strangled a woman -- Jessica Folds -- to death ... and authorities found him dead on June 10 ... his body was in the fetal position next to Jessica's body.

Investigators believe Robbins had a heart attack while disposing of Folds' body.

Newly resurfaced body-cam footage from the Taylor Parker case shows the convicted killer inside an Oklahoma hospital desperately trying to convince officers she had just delivered a baby ... when in fact it was the fetus she had cut out of her murdered friend.

In the footage, obtained by TMZ from the Bowie County Court, investigators are seen at her bedside, explaining the situation at hand -- telling Parker they already are certain she's killed Reagan Simmons-Hancock and stolen the baby out of her uterus ... they're just trying to figure out why, mentioning depression and medication.

Parker appears visibly distressed as she repeatedly insists to law enforcement and hospital staff that she had just gone into labor while driving -- however cops are not buying her narrative, telling her "we know you did it."

Taylor Parker may be on death row ... but while she was in jail awaiting trial she was still playing a doting mother to her daughter over the phone -- and TMZ has the audio.

Take a listen to a prison call -- obtained by TMZ from the Bowie County Court -- between Parker, her daughter Emersyn and her mother, Shona Prior ... the conversation is a far cry from the horrifying case that landed Parker on Texas' death row. Instead of murder and fetal abductions, they're talking campfires, thunderstorms, and early Christmas presents.

The call captures Emersyn excitedly describing sapphire-and-diamond jewelry she received as an early gift ... while also telling her mom that her younger brother, Trey, got a cross chain. Parker reacts like any proud parent ... before the jail's automated system cuts in to warn the call is about to end.

Taylor Parker -- the Texas woman convicted in the shocking "Maternal Instincts" murder case -- is heard claiming to cops she just gave birth to her child, moments before officers realize the darker story.

Parker's chilling encounter with law enforcement is back in the spotlight ... and in the complete, uncut 911 audio obtained by TMZ from Bowie County court, the convicted killer is heard insisting she's going into labor on the side of the road.

Parker told officers and the dispatcher she had delivered a baby in her car, and was desperately trying to get medical help. At the time, cops had no idea they were stepping into one of the most disturbing murder cases in recent memory.

Taylor Parker -- the Texas woman convicted in the shocking "Maternal Instinct" murder case -- appeared to express remorse in a handwritten letter sent to her former boyfriend's father from prison ... TMZ has learned.

In the emotional note, obtained by TMZ from the Bowie County court, Parker directly addresses the father, Jimmy Griffin, of her boyfriend at the time, Wade Griffin, and asked for forgiveness while acknowledging she may not deserve it ... adding "I've asked God for forgiveness and I believe He has showed me it."

Read the letter ... as it offers a glimpse into Parker's state of mind following her arrest in 2020 and prior to her murder conviction in 2022 ... with much of the message focused on faith, family, and her relationship with Jimmy and Wade.

Savannah Guthrie contacted law enforcement earlier this month after she says she learned a controversial YouTube personality was streaming outside her mother's home.

According to police records, obtained by TMZ, Savannah reached out to authorities on June 11 and told them she received information that a YouTuber known as "Criminal Network" was livestreaming and parked in front of the Arizona residence where Nancy Guthrie was abducted.

The report says authorities identified the individual as Alex Zabel from previous investigations.

Police documents state Savannah is one of the responsible parties connected to the property and said she'd been dealing with several internet-based "true crime" vloggers, including Zabel ... and she was "extremely upset" upon learning he was back outside the residence.

Marilyn Monroe's death may not have been suicide at all ... it may have been a far more sinister murder plot that revolves around the Kennedys.

TMZ has produced a new show airing Sunday at 8 PM ET on FOX -- "Celebrity Crime Scene: Marilyn Monroe" -- and it leaves no doubt the crime scene was staged, and people went to great lengths to cover up what really happened to the biggest movie star in the world.

There are massive holes in the official cause of death -- probable suicide -- and we use never-before-seen A.I. to recreate Marilyn's house. Our 3 crime scene investigators blow holes in the official account, but that raises the question ... if not suicide, then what?

Marilyn Monroe did NOT die the way officials claim ... and this will become crystal clear in TMZ's new FOX primetime show ... "Celebrity Crime Scene: Marilyn Monroe"

We use A.I. to create a groundbreaking, never-before-seen replica of a crime scene -- Marilyn's house -- and our crime scene investigators go through all the evidence and blow gigantic holes in the official story.

The LAPD and Coroner say Marilyn died from a "probable suicide." But if she really did OD, where's the water glass in her bedroom? Why are the sheets in pristine condition, given that OD's are ugly? The positioning of her body is not the way she died. Short story ... someone staged the crime scene.

Marilyn Monroe's death wasn't a suicide ... at least according to investigator Paul Holes, who believes powerful people may have played a role in shaping what really happened to the Hollywood icon.

Paul joined us on "TMZ Live" Friday to discuss our new documentary, "Celebrity Crime Scene: Marilyn Monroe" ... and he told us revisiting the evidence behind Marilyn's 1962 death left him with serious doubts about the official ruling.

Paul breaks down what he sees as major investigative failures ... arguing Marilyn's death should've been treated as a homicide until proven otherwise.

The alleged killer of Anna Kepner is exactly where he should be -- behind bars -- so he can't hurt anyone anymore ... this according to Anna's family, who say they are now "at peace."

Anna's loved ones issued a statement to ABC News, saying it was painful to see 16-year-old Timothy Hudson out on bail for as long as he was after being charged with killing Kepner, his 18-year-old stepsister.

Recently, the judge in the case ruled that the evidence against Hudson is overwhelming and revoked his bond, sending him to jail.

Massachusetts mom Lindsay Clancy exhibited "extreme atrocity and cruelty" when she allegedly strangled her 3 kids to death with exercise equipment, prosecutors say.

In a new motion obtained by CourtTV, prosecutors are asking that the 911 phone call from Lindsay's husband, Patrick, be included in their case for her upcoming trial.

Linsday is accused of killing her 3 young children, Cora, Dawson, and Callan by strangling them with exercise bands on January 24, 2023.
