Second-degree murder conviction for death of retired cop in Dorchester

A Suffolk Superior Court jury has convicted Michael "Goody" Collins of killing retired Cambridge police officer Myles Lawton in Lawton's Florida Street home in 2006, the Suffolk County District Attorney's office reports.

Collins was charged with first-degree murder in what prosecutors said was a drug deal gone bad: Collins promised a friend of Lawton's cocaine in exchange for $40,000, but instead robbed and shot him at Lawton's home then fatally shot Lawton.

The jury also convicted Collins of armed assault with intent to murder for the non-fatal shooting and unlawful possession of a firearm. He'll be sentenced tomorrow afternoon.
