Cherelle Baldwin, 21, of Bridgeport, is accused of killing her child's father, 24-year-old Jeffrey Brown, on May 18. Baldwin was arrested Monday after a three-week investigation found no evidence to support her various accounts of what happened, police said.
The investigation found that Baldwin's car traveled 100 feet before striking Brown, apparently accelerating the entire time and with no signs of braking, police said. Police spokesman William Kaempffer told the Connecticut Post that the impact pushed the wall back more than 10 inches.
Brown was pinned between the car and wall when police and firefighters arrived. Attempts to revive him were unsuccessful, police said. Baldwin suffered a leg injury when the car hit Brown and the wall, police said.
Baldwin was detained on $1 million bail and was expected to be arraigned Tuesday in Bridgeport Superior Court. It's not clear if she has a lawyer.
Police Chief Joseph Gaudett Jr. said it took a few weeks for authorities to determine that criminal charges were warranted.
"Detective Heitor Teixeira interviewed a large number of people to get a clear understanding of what happened, and work by the Crime Scene Unit and accident investigators was key to getting to the truth," Gaudett said in a statement.
Police said they are treating the case as a domestic homicide.
