El Centro police and the county Coroner's Office are investigating the death of an El Centro woman, according to police Lt. Tim Blankenship.
Police and coroner's officials said this morning they were unsure what caused the death of Regina Smith, 39. Blankenship said for that reason the case is being dealt with as a homicide.
County Coroner Investigator Rick Williams said on Saturday an autopsy will be done to try to determine the cause of death.
Shortly before 8 a.m. Wednesday police responded to a residence in the 1700 block of Main Street where Smith died at some point between Tuesday night and Wednesday morning.
