Psychiatric patient accused of murdering roommate

The man who killed his psychiatrist in Bethesda in 2006 was charged Friday night with murdering his roommate in a Howard County psychiatric hospital. Maryland State Police said Vitali Davydov, 24, the Gaithersburg man who beat his psychiatrist to death at age 19, came out of his room around 2:30 p.m. Friday and asked for help. Staff members entered and found Davydov’s roommate, 22-year-old David Rico-Noyola, on the floor bleeding, with trauma to his head and body. He was declared dead by an emergency room doctor.

Authorities detained Davydov and charged him later that night with first and second degree murder.
