A man from Hermon who shot and killed an intruder in his home last year told a jury Wednesday he used drugs but he never sold them. 25-year-old Daniel Williams is on trial in Bangor for aggravated trafficking in scheduled drugs and trafficking in drugs with a firearm.Prosecutors say last February some people went to Williams’ apartment and bought drugs.The next day, 30-year-old Robert Dellairo and 19-year-old Philip McIntyre, both of Bangor, broke in and Williams says he shot them to protect himself.Dellairo later died at a hospital. Williams has not been charged in that case.Wednesday in court, Williams admitted that some of the drugs found in his apartment after the shooting were his, but they were only for personal use. He says he didn’t know some of the drugs were mixed with bath salts, either.Both sides wrapped up their case late in the afternoon. It’s set to go to the jury Thursday morning.
