He was. "We cornered one suspect and we tried to negotiate for several hours. Negotiations broke down. We had an exchange of fire with the subject. We saw no other option but to use our bomb robot..."[1] Also he wanted to "kill more" officers, and it sounds like he confessed to killing the police officers.[1,2] Though killing him was legally justified, the use of a robot is troubling.
