Friends of Colin Koehler are painting a very different picture of the accused killer. As the defense began presenting their case this morning they called Koehler’s friends one at a time.Joe Dileone of Connecticut described Koehler as “kind and gentle.” When defense attorney Peter Cyr of Portland asked Dileone about his reaction to the news Koehler had been charged with murdering 19-year-old Holly Boutilier Dileone said, “Everyone was in shock. When you know someone you trust, that’s kind and gentle, it just couldn’t be my friend.”Wendy O’Brien of Bangor told jurors she used to let Koehler take her young daughter to the park to play. She said under direct examination she “had never seen him (Koehler) get upset or raise his voice to anyone.”During cross examination Attorney General Donald Macomber tried to remind the jury of the previous testimony. Macomber asked all of the defense witnesses the same questions. “Are you aware an eye witness has testified that Colin Koehler plunged this knife into Holly Boutilier’s abdomen?” “Yes,” replied O’Brien. “Is it hard to believe a friend could do something like that?” Macomber asked. “Yeah,” O’Brien said.Kohler is expected to take the stand at some point today.
