A man who had warned he would someday kill someone sprayed a street with gunfire, killing two people, then barricaded himself inside his house for five hours before apparently committing suicide, police said.

Barry W. Kaiser, whose wife had obtained a court order barring him from their house, was found dead after police stormed the home Wednesday.Among those killed in the five-hour rampage in the middle-class neighborhood was a police officer. Six people were wounded, two critically.

Police Chief Dennis Garrett said Kaiser, who would have been 36 Thursday, barricaded himself inside the house in 1988 but wasn't prosecuted because of a "mental condition." That incident ended peacefully.

"This is a real tragedy because we've been investigating these incidents involving Kaiser for a long time," Garrett said. "In fact, he told us one time that someday he'll kill someone."
