Twenty-one-year-old Cherelle Baldwin of Bridgeport was arraigned on a murder charge in state court Tuesday in the death of 24-year-old Jeffrey Brown, the father of her toddler son.
She's detained on $1 million bail.
Police say Baldwin ran down Brown with her car and crushed him against a wall in Bridgeport on May 18.
She was arrested Monday after a three-week investigation.
Baldwin's cousin tells WFSB-TV that Baldwin and Brown had a history of domestic violence and Baldwin was trying to save her own life after being choked by Brown.
Brown's family denies that claim.
