A Suffolk Superior Court jury has convicted Michael "Goody" Collins of killing retired Cambridge police officer Myles Lawton in Lawton's 91 Florida St. home in 2006, the Suffolk County District Attorney's office announced.

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 actually reached its verdict Friday, but the judge delayed the reading of the verdict when a defense attorney fell ill.

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

Lawton, who had retired from the Cambridge Police Department in the 1990s, was working in construction at the time of his death.

His son, also named Myles, became a Boston police officer in 2005. "He wanted to be a cop like his father," said Vanessa Jones, whose sister Theresa was Lawton's girlfriend. "Tony always talked about his son."
