Benjamin Davis, 29, has a history of violence. He served two years in prison for choking a family member in 2018. Deputies said he opened an account on an app called Grindr to find people to rob.
Police said Davis told detectives that he used a scarf to strangle him.
According to deputies, Davis told investigators that he arranged to meet a man, identified as Victor Najera Betanzos, at the man’s west side apartment, ostensibly to have sex, but the real motive was robbery. According to deputies, Davis told them he turned on Betanzos once he was in his apartment, knocking him unconscious.
