The San Diego man accused of killing one woman and wounding seven other people at a weekend birthday party called a former girlfriend after he’d begun shooting. Peter Selis, 49, opened fire during a party Sunday at a San Diego-area apartment complex’s swimming pool. Police shot and killed him around 6:13 p.m. when he pointed a gun at officers. After shooting two people, Selis, a resident at the complex, called his ex-girlfriend to tell her what he'd done. Police said Selis wanted his ex-girlfriend to listen in as he carried out his rampage.
