Concord Police Investigate Suspicious Death At Best Western Hotel

CONCORD, CA — UPDATED: An investigation is underway into the death of a woman this weekend at a Concord hotel, according to police. Officers were initially dispatched at 10:42 p.m. Sunday to a report of a physical assault inside a room at the Best Western Heritage Inn at 4600 Clayton Road, Concord police Lt. Nick Gartner said.

Medical personnel tried to revive the woman — identified as 24-year-old Guadalupe Riggi, of Fresno —but she was pronounced deceased at the scene, police said.

Her death is being investigated as suspicious. Detectives were on scene overnight following leads, and as of Monday afternoon were questioning a person of interest in the case.

"Officers and investigators worked through the night to track down the 911 caller who had left the scene prior to the arrival of first responders," Concord police said in a statement.

The Concord Police Department issued a be-on-the-lookout (BOLO) alert for a car suspected to be driven by the caller, and within hours the caller and his car were located several counties away, police said.

The caller was arrested and was being detained on unrelated charges at a jail outside of Contra Costa County, Concord police said.

Concord investigators interviewed the man about the death and were continuing Monday "to analyze his involvement with this investigation as new information is learned," police said.

The cause of the death is currently under investigation.
