BANGOR, Maine (AP) — Jurors in Maine are hearing testimony in Bangor in the death of a woman whose body was found in an abandoned and cluttered railroad shack under the I-395 bridge.

Prosecutors contend 35-year-old Colin Koehler of Bangor stabbed Holly Boutilier in the abdomen and slit her throat. But the defense is pointing toward another man who says he was present at the time of the killings and who accepted a plea deal in exchange for his testimony.

Boutilier’s bloody body was discovered Aug. 9, 2009, by a transient.

The Bangor Daily News quotes a prosecutor as saying Monday that before the killing Koehler practicied stabbing a figure he had drawn on a sheet of plywood.
