DELAND, Fla. -- A Central Florida woman whose 17-year-old daughter was killed in a murder-suicide apparently committed by her ex-boyfriend said the teen was told by police to stop calling for help or she'd be arrested.

Police said Clay Coffner shot his estranged girlfriend in the head outside her DeLand home Friday before turning the gun on himself.

Hall's mother, Sherry, said her daughter was concerned about Coffner and informed police.

In fact, Hall said her daughter called police so much that on Jan. 15 they threatened her.

"The police officer said if you call us one more time on him, I'm going to arrest you both," Sherry Hall said. "So, the day she died, she knew she couldn't talk to police. So, she handled it herself."

Michele Karpowicz said everyone noticed the warning signs before the homicide -- except police.

"I was going crazy," Hall's best friend said. "He was psycho, jealous and abusive."

Local 6 is trying to obtain a police call log to determine how many times the teen called police.
