ORLANDO, Fla. (CNN)--An Orlando police officer was killed Monday and a manhunt is under way for the gunman who shot her, the Orlando Police Department said.

"The Orlando Police Department family is heartbroken today," OPD tweeted along with video of a flag-draped casket. "One of our own was taken in the line of duty. There are no words."

The department identified the slain officer as Master Sgt Debra Clayton, a 17-year veteran of the force.

Authorities have identified the suspect as Markeith Loyd.

At least 14 schools are on lockdown as the manhunt continues, Orange County Public Schools said.

Authorities say a deputy sheriff was also killed on Monday in motorcycle crash while searching for man Loyd, the Associated Press reports.
