HAYWARD -- Police on Monday were looking for a third suspect after a failed Cherryland home invasion robbery in which a suspect was killed.

The suspect is one of three armed people who reportedly forced their way into a home in the 21000 block of Western Boulevard on Sunday evening and demanded cash from a 23-year-old man who lived there, Sgt. Eric Melendez said.

During the hold-up, the homeowner shot two suspects -- a 25-year-old man and a 26-year-old woman -- and killed the man, police said.

As of Monday, the name of the man who was killed had not been released because officials were trying to reach his family, police said. The man's autopsy was set for Tuesday, an Alameda County coroner's office spokesman said.

Police on Monday were looking for the third suspect, a woman, who apparently escaped unharmed, Melendez said.

Officers responded at 5:28 p.m. to the home near Cherry Way for a report of a man who had been shot during an attempted home invasion robbery. They found the man inside the home with multiple gunshot wounds.

The 23-year-old resident was home with a friend when the three people with handguns forced their way inside and demanded money, police said.

"A confrontation broke out, and the victim, who also had a gun, was able to fire rounds that struck the man and one of the women," Melendez said.

The man died at the scene, and police recovered at least one of the guns used in the home invasion.

Both women ran from the home, but at 5:47 p.m., police dispatchers received a call from a hospital that a woman with a gunshot wound had been dropped off there.

Police believe the woman may have been involved in the robbery and are investigating.

The woman was hit by one bullet, which exited her body, Melendez said.

As of Monday, she remained hospitalized in critical condition and had not been arrested.

"We expect her to be in the hospital for a while," Melendez said.

Police are asking anyone with information about the incident to call 510-293-7034.
