DNA matched victim’s profile

WORCESTER A DNA profile matching Aaron A. Gibeaults was found on a pair of blue jeans recovered by police from the home of Jose E. Colon, Mr. Gibeaults accused killer, a Worcester Superior Court jury was told Monday.

Marisa Roe, who formerly worked as a DNA chemist at the state police crime laboratory, testified that forensic testing she performed in 2006 showed that a genetic profile derived from a yellow stain on a pair of blue jeans investigators seized from an apartment at 15 Oxford Ave. in Dudley, where Mr. Colon was living, matched Mr. Gibeaults DNA profile.

Ms. Roe said the chances of such a match occurring at random were one in 20.9 quadrillion in the Caucasian population.

Mr. Colon, 29, is on trial on a murder charge in the slaying of the 18-year-old Mr. Gibeault, whose battered body was discovered near railroad tracks off Oxford Avenue in Dudley on July 23, 2005. Mr. Gibeault died from blunt force trauma and multiple stab wounds.

Kristin Wilson of Webster testified earlier in the trial that she was with Mr. Colon, Mr. Gibeault and others in the area where Mr. Gibeaults body was found either late on the night of July 22, 2005, or early the next morning. She said she saw Mr. Colon throw a rock at Mr. Gibeault that struck him in the face.

Mr. Gibeault, who was intoxicated, fell to the ground after being struck and Mr. Colon continued to throw rocks at him, according to Ms. Wilson, who said she left the area a short time later.

Ms. Wilson said she saw Mr. Colon several hours later with reddish stains on his shirt and jeans. She testified that Mr. Colon washed his clothing at a self-service laundry and that the stains turned yellow.

State Police Sgt. Michael Sampson testified Friday that he recovered a pair of jeans with a yellow stain on the lower right leg portion during a July 25, 2005, search of an apartment at 15 Oxford Ave. in Dudley where Mr. Colon was staying. Sgt. Sampson said he found the jeans under a couch in the living room of the one-bedroom apartment.

Under cross-examination by Mr. Colons lawyer, Calvin C. Carr, Sgt. Sampson agreed that there were others present in the apartment at the time of the search and that he was not certain to whom the seized jeans belonged.

Dr. Richard J. Evans, a pathologist called to the stand by Assistant District Attorney Daniel J. Bennett Monday afternoon, testified that Mr. Gibeault died as a result of blunt head trauma and stab wounds.
