Orlando Master Sgt. Deborah Clayton was shot and killed early Monday morning. At least 13 schools are on lockdown and a massive manhunt is underway as Orlando police hunt the cop killer.

Clayton was shot shortly after 7 a.m. Eastern, and the Orlando Police Department indicates that she died at 7:40:

A manhunt for Lloyd is underway, and First Coast News reports law enforcement has “swarmed the Pine Hills neighborhood, near Pine Hills Road and Clarcona Ocoee Road”–the location of the Walmart near which the officer was killed. Thirteen area schools are on lockdown:

An unidentified Orange County sheriff’s deputy died during a motorcycle crash while participating in the manhunt. Details on the accident were not released.
