Moment monster mum who murdered her own son Logan, 5, stars in chilling homemade slasher movie and finds dead body

LOGAN Mwangi’s murderer mother appeared in a terrible home-made slasher film in which she found a “dead” victim.

Years before she murdered the five-year-old, the monster featured in an amateur film.

Williamson, 31, is seen entering a residence as spooky music plays in the background.

While walking into the modest-looking home, she calls out, “Diana, have you taken your medication?”

She gets a bottle of tablets and a glass of juice before the phone rings after she receives no response.

“Is Ollie in?” says a threatening voice on the other end of the line. In her Essex accent, Williamson informs him he has the wrong number.

Diana is later discovered dead on the sofa, her neck cut beneath a comforter.

The phone rings again, and she pleads for assistance, only to be ordered to search in a cabinet by the same evil voice.

She then comes to an Odeon theatre employee called Ollie who has had his neck cut as well.

Williamson, the daughter of a stockbroker, was a budding filmmaker in Essex at the time.

Her blatant behaviour when screaming for rescue while fraudulently reporting Logan missing is echoed throughout the film.

The creature began “hyperventilating” down the phone and was heard “wailing and yelling” as she claimed Logan had been abducted during the terrifying conversation, in between heaving false cries.

“Get me my baby back,” she yelled at one point.

In actuality, the boy had been beaten to death and left like “fly-tipped garbage” in a nearby river.

Williamson, her partner John Cole, and a 14-year-old child were found guilty of Logan’s murder.

On July 31, last year, he was slain at home before the sick three concocted a “elaborate farce” to conceal his death.

Williamson also wailed “it’s my fault” in terrifying police bodycam footage as she blatantly feigned she had no knowledge of her son’s murder.

After fraudulently reporting Logan missing, the horrible mother can be seen flailing her arms and falling to the ground.

“Why am I not allowed to see my own biological son?” Williamson screams as Cole attempts to calm her down.

“Why is he unconscious?” says the narrator.

“Why isn’t anyone informing me what’s going on?” she continues.

“He’s my baby, what’s going on?” Williamson screams as he crumples to the ground.

The video then cuts to a mother outside smoking, begging with an officer that the lifeless Logan requires her help.

“He requires my assistance,” she adds. He need warm clothing and the presence of his mother.

“It makes me feel so worthless to be standing here.”

“This is all my fault,” Williamson continues, her hand to her head as she sobs.

Caroline Rees QC, the prosecutor, said she “acted the role of a devastated mother to the best of her skills.”

Logan’s body was retrieved from the river with “serious injuries” compared to a “high velocity” automobile collision or a “fall from a tremendous height.”

In addition to internal organ and brain trauma, the kid had 56 exterior injuries from “blunt force trauma” to his head, face, body, limbs, and legs.

A shattered shoulder, major bleeding on the scalp and back of his skull, and a significant brain damage were among the horrible injuries.

Logan had been so badly pummelling that his tongue had been damaged, yet he remained alive for several agonising hours after his liver and colon had been ripped apart.

On a later date, Williamson, Cole, and the adolescent will be sentenced.
