DA: Chelsea Police Acted Within Rights In Stun Gun Death

The Suffolk district attorney's office says Chelsea police acted lawfully when they used a stun gun on a man acting violently who later died at the hospital.

District Attorney Daniel Conley said in his final report released Monday that officers "acted reasonably and lawfully" when they used a stun gun on Dominic Graffeo inside his apartment in June 2014.

Officers were dispatched to Graffeo's rooming house after the manager called to complain that the 56-year-old man was smashing things and "going crazy."

Police say Officer David Delaney used the stun gun on Graffeo after he threw objects at officers that included bottles and a dresser drawer.

The medical examiner ruled that many factors contributed to Graffeo's death, including drug and alcohol use.
