BOSTON - State Police Colonel Richard D. McKeon, Boston Police Commissioner William B. Evans, and Suffolk County District Attorney Daniel F. Conley said today that warrants charging a Dorchester man with the homicides of Scott M. Stevens, Jr., and Michaela Gingras have been lodged at the Suffolk County Jail, where he is currently held without bail in unrelated cases.

The warrants, obtained late last night, charge Lance Holloman with murder, armed assault with intent to murder, and other offenses for allegedly shooting Stevens, 32, and a 54-year-old relative as they rode their motorcycles southbound on Route 93 near the Neponset Avenue exit at about 5:00 Sunday evening. Stevens, a resident of East Taunton, died of his injuries at Boston Medical Center on Wednesday; his relative is expected to survive.

The warrants also charge Holloman with murder for Gingras’ fatal shooting. The 24-year-old resident of Manchester, New Hampshire, was found with fatal gunshot injuries several hours later inside a residence on Santuit Street in Dorchester. She was pronounced dead at the scene late Sunday night.

The charges reflect around-the clock investigation by and communication between the Boston Police Homicide Unit, which responded to Santuit Street, and the Suffolk County State Police Detective Unit, which has jurisdiction over death investigations on State roadways within the City of Boston. Commissioner Evans, Colonel McKeon, and District Attorney Conley stressed that the investigation into both incidents remains very active, and anyone with information on either one is urged to share it with Boston Police at 617-343-4470 or State Police at 617-727-8817.

Holloman was arrested by Franklin Police on three outstanding warrants following a motor vehicle collision early Monday morning. One of the warrants charged unlawful possession of a firearm for a May 31 incident in which he allegedly directed another person to throw a loaded handgun from a vehicle while fleeing a traffic stop; Holloman evaded police but a warrant issued for his arrest.

Holloman was arraigned Monday afternoon in Dorchester Municipal Court, where Judge James Coffey imposed $150,000 cash bail on the gun case, revoked Holloman’s bail for 60 days on an unrelated pending case charging assault and battery and animal cruelty, and imposed an additional $500 bail on an unrelated pending case charging operation of a motor vehicle with a suspended license. Holloman had earlier failed to appear in court on both these latter cases, triggering default warrants in both.

Because he is held on high bail in one case and his bail is revoked in another, Holloman will be brought into court for arraignment on the murder and attempted murder charges on a future date that has not yet been scheduled.
