BEVERLY HILLS -- A 34-year old woman accused of stabbing four people at a Target store in West Hollywood in May has been found mentally incompetent to stand trial.

Layla Rosette Trawick was ordered to be sent to Patton State Hospital in San Bernardino on Wednesday after doctors agreed that she was incompetent, according to Shiara Davila-Morales of the district attorney's office.

The Northern California woman pleaded not guilty to four counts of attempted murder and five counts of assault with a deadly weapon back in the May 3rd rampage.

Police said she took a butcher's knife and chef's knife to the Target, where she roamed the aisles talking about her bipolar disorder and randomly stabbing people, including a woman holding a baby.

Four people were wounded, one critically.

Her mother says Trawick suffers from bipolar disorder and schizophrenia and that she has been trying to get her daughter help.

"I've been trying to get her institutionalized for years, and the mental hospitals just keep releasing her. She's been in and out of them since she was 16," said Trawick's mother.

Trawick's half brother, Tim Helton, told reporters that she had gotten a divorce about five years ago and lost custody of her son soon after.

Helton, a Marine who returned from Afghanistan a week ago, said he lost contact with Trawick about two years ago and her mental health seemed to be deteriorating.

According to Helton, his sister is a generous person with a docile nature.

He says for her to have stabbed anyone would have been completely out of character.

"Being aggressive was not her, she was pretty damn docile," Helton said.

"She might not have all been there upstairs sometimes, but she was never aggressive."

That all changed Monday when Sheriff's officials say Trawick went on a rampage, stabbing three women and a man.

A fifth person was injured as panicked customers ran from the store.

A mother holding her baby was stabbed in the neck and was taken to the hospital, where she was in stable condition, Los Angeles County sheriff's spokesman Steve Whitmore said.

The baby was unhurt and all of the victims are expected to survive.

The sheriff's office said Trawick started stabbing people, apparently at random, on Monday afternoon.

Deputy Clay Grant Jr. was off-duty and picking up a couple of household items from Target when customers started screaming.
