Theodis Keys Jr., 33, is charged with one count of murder.
Keys turned himself in at about 4 p.m. Wednesday, roughly two hours after Lorie Miller, 33, of Sandusky, was found dead at a residence at 114 E. Follett St.
Authories had a short-lived scramble to find a black 1999 Taurus being driven by the suspect, until Keys showed up at the Erie County Sheriff's Department.
Officials from the Bureau of Criminal Identification and Investigation were called to assist Sandusky Police and Erie County Sheriff's Deputies in the investigation.
Police said Keys was Miller's boyfriend.
