As the homeowner went to check out the noise, one of the suspects saw him and shot the homeowner three times.At least one and maybe two other miscreants drove away. They may have also been injured.
But as they were leaving, the homeowner got his own gun and shot the suspects, killing one and seriously inuring the second.
Self-defense works, even after you have been shot.
Both injured people were taken to the hospital in critical but stable condition.
