Police say one police officer was shot and killed and another was gravely injured by gunfire while checking suspicious people in central Florida. Three suspects are in custody and a fourth is being sought.

Kissimmee Police Chief Jeff O’Dell said at a news conference early Saturday morning that officers Sam Howard and Matthew Baxter were checking people in an area of Kissimmee known for drug activity when they were shot. They did not have an opportunity to return fire.

O’Dell says Baxter died later in a hospital, and Howard was in serious condition.

O’Dell said Baxter was a three-year veteran and Howard is a 10-year veteran. Both men are husbands and fathers.

“Right now, as you can imagine, (the families) are completely heartbroken and devastated,” O’Dell said.

Authorities in northern Florida say two police officers have been shot in Jacksonsville.

The Jacksonville Sheriff’s Office said on its official Twitter site that two police officers were shot in the west side of the city. The officers were responding to an attempted suicide call.
