The woman found dead under Newport Beach's Bay Bridge this week died of a gunshot wound, an autopsy confirmed Wednesday.
Officials had called the death of 28-year-old Nancy Hammour "suspicious" since passersby found her body Monday morning, but Newport police have reclassified the case as a homicide, said department spokeswoman Jennifer Manzella.
At 8:45 a.m. Monday, police responded to a call about a body found underneath the Bay Bridge near East Coast Highway and Bayside Drive.
When officers arrived, they determined Hammour, who lived in Santa Ana, was dead.
Police closed portions of East Coast Highway and Orange County Sheriff's Department divers scoured under the bridge.
Manzella declined to say whether divers found anything or release any more information, citing the ongoing investigation.
Orange County Superior Court records show Hammour ran afoul of the law in her past.
In 2008 she pleaded guilty to misdemeanor prostitution and drunk driving charges.
