Medical examiner testifies Madbury teen was stabbed in brain, lung
DOVER - The Maine medical examiner who was assigned to autopsy Aaron Wilkinson's corpse - after his body was found on a rural road in Lebanon - testified Monday during the Tristan Wolusky murder trial.
Dr. Margaret Greenwald talked about the 22 stab wounds 18-year-old Wilkinson suffered on June 21, 2014, the night Wolusky and two co-conspirators allegedly tried to rob him for drugs and money outside his Madbury home.
Greenwald said there were four stab wounds to the back of the head. The first went into the base of Wilkinson's tongue. The rest went right through his scalp, and into his brain.
Wilkinson was also stabbed in the lung, kidney and spine.
Greenwald told prosecutor Stacey Kaelin she found evidence that might suggest Wilkinson tried to defend himself as he was thrown to the ground and attacked face-down.
"We look for defensive wounds on the hands or the extremities in general, because they generally occur when a person is trying to protect their face, their chest. So wound number twenty, which you can see up here on the right arm, could be from moving his arm around to protect himself," Greenwald said.
Other wounds found on Wilkinson's legs could have also been from him struggling to save his life.
Greenwald said that Wilkinson "certainly" felt pain during the stabbing, but likely died within minutes of the attack.
Wolusky's attorney, Mark Sisti, asked Greenwald about what she observed. He claims it was Zachary Pinette and Michael Tatum who executed the killing, after finding out Wilkinson did not have a stash of drugs or money.
"There is no evidence that indicates that three individual people caused these wounds?" Sisti asked Greenwald.
"There's no way, looking at the individual stab wounds, to separate out one person from another at all," Greenwald responded.
"Quite frankly, it could have been caused by one person?" he asked.
"It's possible," Greenwald said.
"It could have been caused by just two people?" Sisti asked.
"Yes," Greenwald responded.
Also testifying on Monday was Sergeant Robert Farrell of the Strafford County House of Corrections. Farrell was assigned to search Tatum's cell for a letter from Alexandria Wyant, who has been charged with conspiracy to commit witness tampering.
Farrell's boss, Capt. Christopher Brackett took the witness stand before testimony ended for the day. He talked about separating prisoners in his county jail, phone calls and visitation rights.
Brackett is expected to resume his testimony on Tuesday. Pinette and Tatum may be called to the witness stand this week.
