A woman died while in custody at the Stanislaus County Public Safety Center on Wednesday.
It's not clear what caused Leslee Laffoon's death. She was arrested Wednesday about 12:50 p.m. on suspicion of violating probation and died that afternoon while she was waiting to be booked at the jail, the Sheriff's Department said.
The department identified her as a 37-year-old transient from Modesto.
She reportedly was admitted into a hospital Saturday complaining that she felt pain all over her body. She was discharged Wednesday and arrested shortly afterward.
The Sheriff's Department said Laffoon was given a medical screening and placed in a holding cell. Another inmate shared the cell with her.
When deputies went to retrieve Laffoon, they found her unresponsive. They attempted to resuscitate her, but could not. She was pronounced dead at 5:31 p.m.
Homicide detectives are investigating her death. The Sheriff's Department said Laffoon was not involved in an altercation with deputies during or after her arrest, and the department does not believe she fought with the cellmate.
An autopsy was conducted Thursday, but results will not be available until toxicology results are completed.
