LEWISTON — A man captured Monday in connection with a
recent killing in Boston has no connection to the August
slaying of Erica Field, but investigators said Wednesday leads on the Field case were “promising.”

Gregory Knight, 27, was arrested Monday night in an apartment at 928 Lisbon St. He was charged with murder in the shotgun slaying of another man who was gunned down in the Roxbury section of Boston last week.

Cooperation between Boston and Lewiston police in tracking Knight was not hard to come by — since late August, the two departments have been working together in an attempt to solve the killing of Field, a 29-year-old Lewiston woman who was shot to death in Dorchester.

Lewiston police Chief Michael Bussiere said investigators were confident there was no link between the recent shooting and that which left Field dead and her boyfriend critically wounded.

“We’ve found no connection at all between the cases,” Bussiere said.

On the night of Aug. 25, Field was found dead in a rental car parked on Norwell Street in Dorchester. Next to her, 32-year-old Shameek “Jo Jo” Garcia had been shot several times, at least once in the head.

Garcia survived the attack and has been recovering at Boston Medical Center.

Bussiere said his department had been working closely with homicide investigators from Boston ever since. They gather at least once a week to go over new findings and lately, the investigation has turned fruitful.

“We’ve got a couple officers who have been assigned to the case,” Bussiere said. “It’s been an ongoing investigation and the leads are promising.”

Pressed on whether he expected an arrest in the Field killing, Bussiere declined to provide more details. He did, however, suggest that there was no cause for concern that a killer was roaming at large.

“We’re confident,” Bussiere said, “that there is no danger to the public at this time.”

Field, the mother of a sixth-grade girl, grew up in Lewiston and worked at Val’s Root Beer, a drive-in hamburger stand on Sabattus Street.

In the more recent case, Lewiston police assisted the Boston Police Fugitive Apprehension Unit in the arrest of Knight. The capture of the accused killer was described as uneventful.

However, another man, 35-year-old Trevor Higgins, was charged with assault, accused of striking a Lewiston police detective who had come to assist in the arrest of Knight.

Higgins remained at the Androscoggin County Jail on Wednesday night.
