How Would Ed Owens End Up Under Karen's Fingernails?

In 19 80, steve strom told police that when he arrived at work at 12 forty five a m, june sixth, ed owens wasn't there. The copse back then even took pictures of ed, collected blood and hair samples. And now that some of the d nd a under karen's finger nails turned out to be a match for that sample collected from ed owen's benson's belief about what happened the night of karen's murder took a sudden turn. I believe that it was more or less an opportunity with with ed. He probably drank more than usual and decided that he wanted to go out and get into trouble, get into trouble.
