UPDATE: Listen to Police Radio Response to Stabbing-Suicide

At first, police thought they were responding to a domestic dispute during the wee hours Saturday at a house on the 20200 block of Lassen Street.

But a more horiffic scene unfolded once they arrived. Inside the one-story white house, behind two palm trees and a neatly trimmed lawn, they found a woman bleeding from stab wounds in her neck. And then out back, sinking in the pool was a man. Drowned.

He was identified by the coroner's office Sunday as 59-year-old Carlos Olguin. They did not release his injured wife's name.

You can listen to the police radio crackle with the actual voices of LAPD Dispatch and medics from Chatsworth Fire Stations 96 and 107 as they rush to the rescue in response to what police called an attempted murder-suicide. Just click on the attached video.

The woman was rushed to a hospital and is expected to survive, said Los Angeles police Sgt. John Kielbasa of the LAPD's Devonshire Station.

The first report was that shots had been fired in the area at 2:30 a.m. and police brought in a canine unit and poked through the bushes, accordng to KABC-TV.  Firefighters clambered on the roof in search of a weapon.

KABC-TV reported that there were several rooms for rent at the home, but there were no other details.
