Police said Kerrick was charged with voluntary manslaughter, which under North Carolina law involves killing without malice using "excessive force" in exercising "imperfect self-defence."
Police were not expected to further describe the incident Sunday, CMPD spokesman Officer Keith Trietley said, and a report was not available Sunday.
Kerrick, 27, turned himself in for booking Saturday evening and was released on $50,000 bond, according to the Mecklenburg County Sheriff's Office website. Kerrick joined the police force in April 2011.
FAMU Interim Athletic Director Michael Smith confirmed Sunday that Ferrell played the safety position for the school's football team during the 2009 and 2010 seasons.
"Our hearts and prayers go out to his family during their time of bereavement," Smith said in an emailed statement.
A public records search indicated that Ferrell began living in Charlotte early this year after moving from Tallahassee, Florida, home to FAMU.
Before Kerrick was charged, police chief Rodney Monroe describe the accident in a news conference. He said the wreck was so severe Ferrell would have had to climb out of the back window to escape. Monroe said he didn't know what caused the crash and didn't say whether Ferrell suffered injuries, The Charlotte Observer reported.
Ferrell apparently walked about a half-mile (800 metres) to the nearest house and was "banging on the door viciously" to attract attention, Monroe said. Thinking it was her husband coming home late from work, the woman who lives there opened the door. When she saw Ferrell, she shut it and called police about 2:30 a.m., Monroe said.
Monroe said he didn't think the unarmed Ferrell made threats or tried to rob the woman.
