A Boston police officer was suspended without pay Friday after she was indicted by a grand jury for reportedly misleading investigators about her contact with a Dorchester man accused of killing two people, police and prosecutors said.
Officer Monicka Stinson, 37, of Dorchester, faces charges of witness interference and obstruction of justice, police said in a statement posted to the department’s website.
On Friday, Lance Holloman, 30, was indicted by a grand jury on two counts of first-degree murder in the deaths of Scott M. Stevens Jr., 32, and Michaela Gringas, 24, on Sept. 10, prosecutors said.
Prosecutors said Stinson allegedly lied to Boston police about her contact with Holloman following the shootings.
Stevens was shot while he rode his motorcycle on Interstate 93. Gringas, who is believed to have been a passenger in Holloman’s Jeep at the time of the highway shooting, was found dead in the vehicle several hours later.
Holloman is also accused of shooting and wounding Stevens’ 54-year-old relative while on Interstate 93.
Stinson’s indictment followed an ongoing investigation jointly conducted by the Boston police homicide unit, the anticorruption unit, and the Suffolk County District Attorney’s Office, police said.
Stinson had been placed on administrative leave on Oct. 5, 2017, pending the homicide and anticorruption division investigation, according to the department’s statement. That investigation led to her indictment Friday, police said.
Stinson joined the department in July 2007 and made about $97,000 as a police officer in 2016, according to a city employee earnings report.
In the department statement, Boston police Commissioner William B. Evans warned that incidents like this can “erode the trust” officers work to build each day with the communities they serve.
“I hold my officers to the highest of standards and expect them to cooperate with investigations regardless of any personal connections to those involved,” Evans said. “News of (the) indictment sends a strong message that no one is above the law and that this conduct will not be tolerated.”
Along with Stinson, Holloman’s mother and sister were also charged in the case Friday.
Daphne Holloman, 53, the mother of the suspected shooter, is charged in connection with misleading an investigator. Latoya Holloman, 36, Lance Holloman’s sister, was charged with witness intimidation, prosecutors said.
Lance Holloman also faces a charge of armed assault with intent to murder and two counts of assault and battery with a dangerous weapon, prosecutors said.
