Florida Gunman Slain After Standoff

A lone gunman was shot to death Thursday 13 hours after allegedly killing a sheriff's deputy, wounding two others, and barricading himself inside his camper-trailer.

CBS affiliate WKMG in Orlando has identified the man as 43-year-old Alan Singletary. According to the Seminole County Sheriff's Department, Singletary has a history of mental illness.

Singletary had allegedly kept officers pinned down with heavy gunfire. More than 400 rounds of gunfire were exchanged and 67 rounds of tear gas have been used by Seminole sheriffs, according to WKMG.

WKMG reports that the man was found by authorities under a piece of machinery on his property, after an exchange of gunfire with sheriff's deputies.

The shooting began Wednesday night after a call about a man pulling a weapon in Geneva, about 15 miles northeast of Orlando. Trouble started when Singletary pulled a gun on his landlord, Tony Larson, Sheriff Don Eslinger said Thursday.

WKMG has identified the slain officer as 55-year-old Gene Gregory, a deputy since 1991. He is survived by a wife and three sons.

Injuries sustained by two other officers are not life threatening. WKMG reports that one deputy was shot in the shoulder and a lieutenant was shot in the foot.

About 15 people living nearby were ordered out of the area.

"I thought somebody was running around in the woods shooting at our house," said Ann Huggins, 17, who lives across the street.
