The records make note of gang activity, drug use and larceny.
He served just 90 days of a one-year jail term for a violent attack on his stepfather in 2006.
That year, he was hospitalized at Massachusetts General Hospital and diagnosed with nonspecified psychosis, traumatic brain injury and marijuana abuse.
Chappell was hospitalized again the following year at Bridgewater State Hospital, following his conviction in the assault on his stepfather. At Bridgewater, he engaged in “hypersexualized” and disorganized behavior and attacked another inmate.
After his release from custody, Chappell stopped taking the Risperdal he was prescribed at Bridgewater.
A few months later, he was back at Massachusetts General, after making threats to kill his ex-girlfriend and assaulting a stranger on the street. That is when he was referred to the DMH for services.
However, the report found, he continued to resist treatment, refusing to attend counseling, as his behavior continued to worsen.
In February 2009, Chappell called a female case worker “four or five times” and made “sexually inappropriate and harassing comments” and inappropriate gestures during some meetings with female staff, the report said.
The absence of the program manager from Seagull House contributed to a lack of communication about Chappell’s deteriorating behavior, the report concluded. No one was there to follow up on reports about Chappell’s worsening behavior.
On Dec. 6, 2010, he punched another resident of the Perkins House group home four or five times, and police were called, the report said. After an evaluation, he was returned to the program. Two days later, he began staring in a “sexualized manner” at a female staffer.
After the resident who had been assaulted obtained a restraining order, Chappell was moved to the Chelsea Respite Program, but after more troubling behavior, he was moved to the Seagull House on Jan. 3, 2011.
Less than three weeks later, he murdered Moulton, who had been left alone with him.
