Brian Green was upset and arguing with his girlfriend, Tracey Nicole Green, when she returned to their York Township home early Tuesday morning, police and family members said.

The yelling woke up Tracey's 16-year-old daughter, Anglecia, just before 2:45 a.m.

Anglecia went downstairs to find Brian Green with a

gun and her mother in the garage, according to the account Anglecia told police and her grandmother, Margaret Justice.

Brian Green told Anglecia to go back inside. A few moments later, Anglecia heard three or four shots and ran back into the garage, where she found her mother bleeding. She called 911 for police and remained on the line with an emergency dispatcher who tried to help her tend to her mother's wounds, Justice said.

"She was trying to bring her (Tracey) back. She was holding her. There was blood coming from everywhere. She wasn't sure where it was coming from," Justice said.

Tracey's 9-year-old son, Jason, woke up to find Anglecia holding his dying mother, Justice said.

Once York Area Regional Police arrived at 700 Highlands Path, Anglecia called Justice at her home in Baltimore.

"Nana, mommy is dead," she said.

Justice refused to believe it.

"Yes, she is," Anglecia responded, and police were at the home.

Put the police on, Justice told Anglecia.

"'Yes, I'm sorry. She is dead'," Justice remembers police telling her.

Tracey Green, 38, died of multiple gunshot wounds, according to the York County Coroner's Office. She died inside the garage.

When Justice asked where Brian Green was, Anglecia said he sped away from the house in his car.

Using the vehicle's description, York Area Regional police officer Tobin Zech spotted Brian Green's 1996 Pontiac Gran Prix on Donna Lane, near Queen Street. He placed him under arrest.

Green, 39, of the 700 block of Highlands Path in York Township, was charged Tuesday morning with criminal homicide. He remains in York County Prison without bail.

Police later found a .

380 semi-automatic handgun, covered in blood, inside the car, according to court records. They also found blood in the vehicle and on Green's hands.

Police say the killing was a domestic dispute.

Word of the shooting shook the quiet, upscale, affluent community of Chestnut Hill, where Tracey and Brian Green lived for about 18 months.

"It is just a tragic event no matter where it was at. The hardest part is to see two young children suffer through this as well as the rest of the family," York Area Regional Police Chief Thomas Gross said.

Gross and details in a criminal complaint against Brian Green confirm Anglecia's account of the shooting.

Tracey Green's two children are with family.

Justice said family members are in shock and are preparing funeral arrangements in the Randallstown area of Maryland.

Justice was very close with Tracey, her only daughter, and there was no sign of problems with Brian Green, who Tracey called "Lovie." She said the couple was happy, was together about five years and planned to marry.

There were no previous domestic calls to the home, according to police.

Justice believes Brian Green became angry because Tracey was out all night after visiting her step-sister, Karen, in Baltimore.

"He is a very jealous person. She (Tracey) always said that," Justice said.

Brian and Tracey Green were living the dream, her mother said.

The two had bought a more than $500,000 home in York Township about 18 months ago and the children were doing well at Dallastown Area schools.

Tracey Green worked hard at an assembly plant of General Motors in Whitemarsh, Md., to support her family, her mother said. Brian Green had a good paying job at Office Depot in Odenton, Md., according to Justice and court records.

Justice cried as she spoke about her daughter but said she has to be strong for her grandchildren.

"She was my pearl. She was my everything. I love her so much. I am going to miss her. I will never, in my life, be the same," Justice said.
