SAN LEANDRO -- A man fatally shot last week while defending his mother-in-law from thieves has been identified as 32-year-old Delun Pan, according to the Alameda County Coroner's Office.

Meanwhile, the city of San Leandro is offering a $10,000 reward for information leading to an arrest and conviction in connection with his death.

Pan, of Alameda, was shot about 9:20 p.m. in the 15500 block of Harbor Way. Police arrived to find Pan lying on the sidewalk. He was taken to a hospital but died shortly after he arrived.

A coroner's office spokeswoman said Tuesday that an autopsy revealed he died from a single bullet wound to the abdomen.

Investigators said the woman was unloading items from her car when one of the two thieves attempted to rob her. Pan came out of the house to help her and was shot.

The two suspects then drove away in a dark-colored sedan toward Lewelling Boulevard. Detailed descriptions of the suspects were not provided.

It was the second homicide of the year in San Leandro.

During a city council work session on Monday, Mayor Stephen Cassidy -- at the request of the police department -- asked councilors to approve a $10,000 reward for information leading to an arrest and conviction in Pan's death.

The council voted unanimously to approve the reward.
