BAY CITY, MI — A 23-year-old Bay City man is charged with a felony after police alleged he attacked his pregnant girlfriend with a cordless drill.

About 6:19 p.m. on Sunday, Dec. 15, police responded to a South End apartment in reference to an assault. The person who called 911, Jamie L. Adams, reported that her 19-year-old neighbor, Tyresha M. Humphrey, had come into her unit, bloodied and saying her boyfriend beat her, court records show.

Arriving on the scene, police announced their presence in front of Humphrey’s unit and noticed what looked like two drops of blood on the floor. Shortly thereafter, Humphrey’s boyfriend, Jermaine C. Perkins opened the door. Police ordered him to the floor and placed him in handcuffs.

Humphrey told police she had been living with Perkins for about three months and was five months pregnant with a previous boyfriend’s baby. She said they started fighting and Perkins slapped her, kicked her knee and came at her with an orange Black & Decker cordless drill. Perkins hit her twice in the left arm with the drill and also punched her in the stomach, Humphrey said.

Police noted in their reports, contained in court documents, that Humphrey had two puncture wounds to her left arm. Humphrey was taken via ambulance to McLaren Bay Region hospital for treatment of her injuries.

Interviewed a second time by police, Humphrey said that Perkins had also pinned her down and forced her to swallow three Xanax pills, saying he wanted her to have a miscarriage.

At the time of his arrest, Perkins had a bottle on him containing several blue pills, according to police reports. A paramedic at the scene said he thought the pills were Xanax, police report.

Interviewed by police, Perkins said he does not date Humphrey but was allowing her to stay at his place. He said she attacked him with the drill and he pinned her down to defend himself as she continued hitting and kicking him.

Police wrote in their reports that Perkins had blood on his clothing and left hand, but no apparent injuries.

Bay County Chief District Judge Timothy J. Kelly on Tuesday, Dec. 17, arraigned Perkins on one count of assault with a dangerous weapon, a four-year felony, and domestic violence, a misdemeanor. Two days later, Perkins posted bond through a bonding agency.

Perkins is to appear for a preliminary examination before District Judge Mark E. Janer at 10 a.m. on Monday, Dec. 30.
