Montgomery County police arrested 35-year-old Rohan Goodlett and charged him with two killings that took place earlier this month. Court records show that Goodlett was under mental health supervision from the state after a separate arrest in 2008, but he was not considered to be a danger to himself or others.
Goodlett was later acquitted of those charges. Montgomery County Council Member George Leventhal says the standards to have someone committed to a mental hospital are many times too strict.
"If someone hasn't committed a crime yet, it can't be proved that he is a threat to himself or others. And yet, as we saw in Olney and in Tucson, that individuals become violent who were not committed but who were getting mental health treatment," he says.
Police have yet to determine how Goodlett got the gun he's accused of using in the shootings, as he was barred from owning weapons as part of his treatment.
