The stabbing victim has identified the man who stabbed him as Jesse Serpa, a 33-year-old Hispanic man from Livermore, according to a police news report.
The report was forwarded to the Alameda County District Attorney's Office, which charged Serpa with one count of attempted murder. A no-bail warrant has been issued for Serpa's arrest.
Police arrived on the scene at about 9 p.m. Wednesday after receiving several 911 calls about a stabbing at the complex.
Initial reports indicate that two men began arguing with each other and started fighting. During the course of the fight the suspect produced a knife and stabbed the victim once in the chest, then fled on foot.
The victim, a 30-year-old Livermore resident, was taken to Eden Medical Center for the treatment of his injury, which is non-life threatening.
Serpa is described as a Hispanic male adult with black hair and brown eyes, approximately 5 feet 11 inches tall and about 180 pounds. He was wearing a black shirt or jacket and blue jeans.
While police say the two men knew each other, they have not been able to determine what led to the fight.
Police were still searching for Serpa as of Tuesday.
Anyone with information regarding this investigation or the location of Jesse Serpa is encouraged to call the Pleasanton Police Department at 931-5100.
