Michigan Grandson Begged for 911 Help Before Fatal Shots Recording played for first time at grandmother's trial.

July 3, 2012 -- A Michigan woman accused of fatally shooting her teenage grandson sobbed in court Monday while listening for the first time to the 911 recording in which he desperately tried to call for help.

"I got shot, again," Jonathan Hoffman, 17, is heard telling a 911 dispatcher in tapes that were played in court.

"My grandmother. My grandmother shot me," Hoffman said. "I'm going to die. Help."

The 911 operator can be heard asking where he was hit. In a muffled voice, Hoffman tells the operator that he'd been hit in the chest.

The grandmother, Sandra Layne, 74, cried and rocked back and forth Monday as the 911 tapes were played for the first time since the May 18 murder in Bloomfield Hills, Mich., an upscale suburb outside Detroit

Police say Layne shot her grandson five times and when they arrived at her house, she ran out of the front door with her hands up.

"She screamed to me, 'I murdered my grandson,'" police officer Derrick Kassab said on the witness stand.

Several officers took the stand with similar accounts of the day. After police were dispatched to Layne's home, they testified, they could hear two or three more shots from inside the residence, according to ABC News station WXYZ. Police say the home was littered with bullet casings and blood.

Hoffman had been living with Layne and his grandfather for several months while attending an alternative school. Hoffman's parents were divorcing and living outside of Michigan, according to The Associated Press.

Jerome Sabbota, Layne's attorney, said the grandmother began to fear Hoffman because she suspected he was using synthetic marijuana, called K2, or "spice." Tests showed the drug in the teen's system when the shooting occurred.

Police had been called to Layne's home in March on a domestic disturbance call involving her and Hoffman. No charges were ever filed on that incident, according to WXYZ.

Also in March, Hoffman was pulled over and ticketed for possession of marijuana and drug paraphernalia. He later received a 93-day suspended sentence and was placed on 12 months' probation, according to The Associated Press.

"She [Layne] killed a person that she loved, that she tried to save. There are no winners," attorney Sabbota said. "She's in her own hell."

It could be tricky if Layne decides to argue self-defense because even if Hoffman were under the influence, police were already on the way.

"He was on the line to 911 when three additional shots rang out," ABC News legal analyst Dana Cole said. "So, obviously, he did not pose a danger at that time."

Layne is being held without bond and if convicted, she could face up to life in prison. She's expected to be back in court in a couple of weeks.
