PHOENIX -- New details have emerged in a murder-suicide that left two Phoenix teens dead in March.
Police reports and interviews obtained by 3TV show that 15-year-old Matthew Bolton and 16-year-old Anastasia Greer, both sophomores at Sandra Day O'Connor High School, had an abusive relationship. There were warning signs long before he pulled the trigger on March 7.
"He like picked her up and like threw her on the ground," one girl told police during an interview.
According to police, Bolton shot Greer five times in the front yard of her friend's north Phoenix home after she ended the on-and-off relationship.
He reportedly told her he just wanted to talk but had already left a suicide note. Bolton wrote that he was taking his own life because his parents were emotionally abusive, his grades were failing, and he would never be able to have the only girl he ever loved.
Police said Bolton broke into his brother's locked bedroom to retrieve the gun and offered a friend his computer in exchange for a ride to the home near 43rd Avenue and Happy Valley Road.
Sensing something wasn't right, Greer's friend gave her a pocket knife when Bolton showed up.
"Please come over here right now," Greer's friend told the 911 dispatcher. "There's people dying right now!"
He explained that there had been a shooting and a suicide, while his mother tried to revive Greer with CPR.
"I can't have time right now to talk. I need to help this girl breathe," the mother said. "I don't want her to die."
Earlier that day, rumors circulated that Bolton was on campus with a gun.
One boy told police he thought he saw the weapon. "He lifted his shirt and I thought I saw something that looked like the handle of a handgun."
Greer stayed inside the principal's office and left at the end of the school day, but Bolton tracked her down to her friend's house.
One girl told police, "I knew that he was crazy. I just didn't think he would like, you know, do anything like that."
