The prosecution rested their case Wednesday with witnesses from the Maine State Crime Lab in Augusta. The defense is expected to start calling witnesses Thursday and Colin Koehler could be on the stand as soon as Thursday morning.One of the only bright spots for the defense came yesterday when the prosecution’s star witness, 28-year-old Justin Ptaszynski, admitted that a pair of jeans stained with the victim Holly Boutilier’s blood may be Ptasinzski’s and not Colin Koehler’s. When asked during cross examination on Tuesday whether the blood stained jeans could belong to him Ptaszinski said, “They might be.” However that moment was short lived. Wednesday DNA expert Jenn Sabean testified that a swab taken from fabric of the jeans contained DNA from Koehler and 2 other people but it was not a match Justin Ptaszinski. Ptaszinski has already pled guilty to hindering apprehension in this case and is serving a 6 year prison sentence at the Maine State Prison in Warren. The defense is trying to offer alternative theories of the murder including the implication that it could have been Ptaszynski who murdered Boutilier. Early Wednesday morning the prosecution called Ken Creamer of Hartland to the stand. Creamer is the estranged boyfriend of Koehler’s ex-girlfriend Jessica Palmer. The prosecution has theorized Koehler murdered 19-year-old Holly Boutilier to show his faithfulness to Palmer. Palmer testified yesterday that Koehler admitted to her that he murdered Holly Boutilier last August. Creamer took the stand around 8:45. He told jurors Koehler told him over the phone he murdered Boutilier. “He told me he stabbed her in the stomach…and he cut her throat to shut her up.” Creamer also testified Koehler sent a series of text messages requesting that the two men meet near the site where Boutilier’s body was discovered.Just before the morning recess Detective Timothy Cotton of the Bangor Police Department took the stand. He is one of the lead detectives in the investigation. The jury was shown a video of Colin Koehler at the Bangor Police station the day after the murder. Cotton told the jury Koehler was there to have a protection order he previously filed against Ken Creamer dropped. Video of Koehler filling out the paperwork to have the protection order dropped appears to show Koehler sending and receiving text messages close to the time that the messages were sent to Creamer.Cotton also told the jury that Koehler lied to police about being with, or even seeing, Holly Boutilier on the day she was murdered. The video from an interview police conducted with 35-year-old Colin Koehler the day he was charged with Boutilier’s murder was shown in court late Wednesday morning. On the tape Detective Cotton asked Koehler 16 times during the 3 hour interview if he had seen Boutilier the day she was murdered. All 16 times he was asked, Koehler denied seeing or being around Boutilier on Saturday, August 8, 2009. Surveillance footage taken outside the Bangor Police Department that day shows Colin Koehler walking with Holly Boutilier and Justin Ptaszynski. A man who was serving time in the Penobscot County Jail with Koehler also testified that Koehler told him, in detail, how he killed Boutilier. The defense is expected to start calling witnesses tomorrow morning. Colin Koehler could be on the stand as soon as tomorrow.Stay tuned to WABI TV 5 News at Noon, 5:00, and 6:00 as well as www.wabi.tv for the very latest.
