PORTLAND — PORTLAND — A Gorham woman will serve four years in prison after pleading guilty Monday to two counts of manslaughter for the October 2014 deaths of her boyfriend and 16-year-old son.

According to the terms of a plea agreement, Candice Tucker, 35, was sentenced to two terms of 12 years in prison, with all but four years suspended, and four years probation for the Oct. 19, 2014, crash that killed Eric S. Morey, 35, and Branden Denis, 16.

Two charges of Class B aggravated operating under the influence were dismissed by the district attorney’s office.

Cumberland County Assistant District Attorney Michael Madigan told Justice Nancy Mills on Monday that witnesses and other evidence would have shown that Tucker was driving at 85 miles per hour on Route 302 in Naples the evening of Oct. 19, 2014, when her car crossed in front of oncoming traffic and hit a tree, “essentially splitting the car in half.”

Morey and Denis died at the scene as a result of blunt force trauma. Tucker was taken to Bridgton Hospital, where one blood test revealed her blood alcohol content was .07 and another showed it was .05, Madigan said.

Tucker was indicted in December 2014 on two counts of manslaughter and two counts of aggravated operating under the influence. She faced a maximum sentence of 30 years in prison, a $50,000 fine and four years probation on each count.

But Mills told Tucker and about a dozen members of the victims’ families that although Tucker was previously convicted of operating under the influence in 2002, a number of mitigating factors prompted her to agree to the sentence.

As outlined by Tucker’s attorney, Amanda Doherty, Tucker underwent brain surgery in 2000 for seizures and the surgery “ended up significantly affecting her anxiety levels.” When she later had surgery for carpal tunnel syndrome, she became addicted to Vicodin, Doherty said.

Tucker entered a detox program at Mercy Hospital, Doherty said, and later attended a methadone clinic, but then lost her health insurance. She was awaiting an appointment with a psychiatrist at the time of the crash.

Mills said the factors pointed to “a low likelihood of reoffense,” noting that Tucker had already begun efforts at rehabilitation prior to the crash. Mills said Tucker seemed to find “sparse treatment” for the emotional issues that resulted from her brain surgery and addiction, and said 12 years seemed “fair and reasonable.”
