“Because of the stress that’s on the job, I can only see this kind of behavior continuing over time,” said an anonymous first responder. Preliminary interviews with other employees at Fire Station 81 indicate the shooter and Carlon had “some workplace beef,” said Los Angeles County sheriff’s Lt. Brandon Dean, who is overseeing the homicide investigation. “It sounds like they didn’t like each other,” Dean told The Associated Press, without elaborating. The other victim, identified as a 54-year-old captain who was once an LA deputy, is still hospitalized in critical but stable condition. Hundreds turned out for a memorial for the victims on Wednesday evening. James Claude, an Agua Dulce resident, and his family left flowers Wednesday at Station 81.
