A young mother who was shot by a school resource officer in Long Beach, Calif., was declared brain dead and is expected to be removed from life support on Friday, according to the family's attorney.

Mona Rodriguez, 18, was shot in the head by a Long Beach Unified School District safety resource officer on Monday while inside a car that was attempting to flee the scene of an earlier altercation near Millikan High School.

According to the school district, the school resource officer was responding to an alleged fight between the woman and a 15-year-old girl. When Rodriguez, a man and a boy tried to leave the fight scene in a gray car, the school resource officer opened fire, hitting Rodriguez, Long Beach police said.

Rodriguez was sitting in the front passenger seat when she was shot, police said.

Investigators determined Rodriguez initiated the original altercation and that she and the 15-year-old girl "are known to each other," though the motive for the altercation was unknown, according to police.

Rodriguez's boyfriend of two years and the father of her 5-month-old son, Rafeul Chowdhury, got emotional outside Long Beach Memorial Care Hospital on Wednesday, saying, "I want justice for my girl, my baby momma, the love of my life."

"I want him in jail for what he did to my girlfriend," he said. "She did not deserve it."

Family and friends held a candlelight vigil for Rodriguez Wednesday night.

Prior to the family attorney's update, family members said that the hospital has notified them that she will be removed from life support on Thursday against their wishes. Later in the day, Rodriguez's family attorney announced the young woman will be taken off life support Friday.

Earlier in the week, the family wanted the Attorney General to investigate and wants the officer charged for her death.

The family's attorney said they have no recourse to stop the hospital from disconnecting the young mother from life support.

The hospital has not commented, according to FOX 11 LA.

School officials said no students were hurt in the shooting and that there was no indication any students were involved. No one from the Long Beach Police Department was involved in the shooting.

According to Long Beach police, a 20-year-old man and a 16-year-old boy were also involved in the brawl. However, police are investigating their "participation level" in the fight.
