A 25-year-old Canyon Country woman arrested on a murder charge allegedly has a history of mental illness, according to a homicide investigator Monday.

Jessica Paige Greenback, 25, of Santa Clarita, is due in court Tuesday to face charges in connection with a shooting where she lived on the 18000 block of Danielson Street around 5:30 a.m., officials said.

The weekend shooting that reportedly sprung from a domestic dispute left one person dead, another wounded and a third shot at, in addition to plenty of questions homicide detectives are still trying to answer.

Jessica Paige Greenback, 25, of Santa Clarita, is due in court Tuesday to face charges in connection with a shooting where she lived on the 18000 block of Danielson Street around 5:30 a.m., officials said.

“She killed her brother and shot her dad and she tried to kill another individual in the house, but he was not hurt,” said  Lt. John Corina of the Homicide Bureau of the Sheriff’s Department, adding detectives were investigating her history.

Greenback did not have any outstanding charges, according to LASD records, however, records indicate she’d been committed for mental health concerns several times in her past.

“Right now, it look likes she has a long battle with mental illness,” Corina said. “She’s had several commitments for 72 hours (over concerns about mental health).”

Greenback allegedly shot her 28-year-old brother and her father in the home they shared..

Officials with the District Attorney’s Office said a case has not yet been filed as of Monday afternoon.

Her brother, who was not identified by Sheriff’s Station officials, died of a gunshot wound to the head. The suspect’s father was grazed by a bullet, according to officials.

A semi-automatic handgun was recovered at the scene, and is believed to be the murder weapon.

The reported father of the victim, a 56-year-old man, sustained injuries consistent with a graze wound to the head, but is expected to survive, according to Santa Clarita Sheriff’s Station deputies.

Both victims were taken to the hospital.

Homicide detectives are in the process of determining the motive in the shooting, according to a press release from the Los Angeles Sheriff’s Department.

Greenback made several strange claims and appeared “delusional,” Corina said.

Greenback could face murder and attempted murder charges, Corina said.

Homicide detectives were not immediately available for comment on the investigation.

A Coroner’s official had not yet completed an examination as of Monday afternoon, and therefore could not release victim identification.

More information will be added as it becomes available.
