OAKLAND (CBS/AP) - Oakland police were searching Monday for a shooting suspect who fled his own house after officers said he fatally gunned down one man and wounded another after an argument.

Police said 31-year-old Douglas K. Yim Jr. invited the two unidentified men to his house Saturday to hang out.

Yim's mother called police when she found the 25-year-old man dead at her son's rented home.

Police said the other victim, a 35-year-old man, drove to the hospital for treatment and was later released.

Details about what caused the argument were not released by police, who offered a $15,000 reward for information leading to Yim's arrest.
