In most jurisdictions that I know of, you cannot go out hunting for the burglar and shoot him and still call it 'self defense'. Unfortunate circumstance - I don't think anyone would be sorry to see a scumbag burglar gone, but this isn't the way to go about it.

Arlington burglary victim accused of murdering burglar
ARLINGTON, Wash. Snohomish County sheriff's detectives say a burglary victim is now a murder suspect after allegedly killing the burglar, hours after the crime.
Keira Earhart, 38, appeared in court Thursday on investigation of second-degree murder.
It all started Monday at Earhart's home in the 22800 block of 37th Avenue Northeast in Arlington.
"He saw the suspect running out of his house and he called 911 to report that," said Snohomish County Sheriff's spokesperson Rebecca Hover.
A couple hours later, a half-mile down the road, Earhart spotted the same man hiding in a ditch. A neighbor said Earhart had a gun and yelled for the burglar to stop. As the burglar took off towards the woods, Earhart allegedly fired, what he would later tell the neighbor, were two warning shots.
