FERNANDINA BEACH, Fla. (AP) — A man who had been ordered to stay away from his ex-wife fatally shot her and her brother-in-law and injured her sister before turning the gun on himself, authorities said.

Denny O'Dell Taylor Sr., 60, died outside a school Thursday from a self-inflicted gunshot wound to the head, said Nassau County Sheriff Tommy Seagraves. Shortly before that, Taylor confronted his former family in the parking lot of a nearby hospital, Seagraves said.

Roy E. Rogers, 67, died outside Baptist Medical Center-Nassau.

The gunman's ex-wife, Frances Stephens Taylor, 55, was flown to Shands Jacksonville hospital, where she was later pronounced dead.

Her sister, Sara C. Rogers, was in serious condition Friday morning at Baptist Medical Center, hospital officials said.

The family had a history of domestic violence, and an injunction had been issued ordering the gunman to stay away from his former wife and her sister, authorities said.

"We're still trying to piece this thing together," Seagraves said.

School officials said there were no injuries to students or personnel at Emma Love Hardee Elementary School, where Seagraves said Taylor shot himself in the parking lot as deputies arrived.

The school was placed on lockdown, but parents were allowed to pick up their children early, said Sharyl Wood, executive director of administrative services for the Nassau County School Board. School psychologists were sent there for anyone needing counseling, she said.

Fernandina Beach is a wealthy resort area, about 35 miles northeast of Jacksonville.
