AUGUSTA — When Maine State Police detectives entered the Chelsea home where a teenager is accused of killing two men and injuring a woman, they found signs of violence, a journal depicting a deadly act, an ax and security cameras that had been turned toward the wall.

That testimony came on the third and final day of the bind-over hearing at the Capital Judicial Center to determine whether the teen will be tried as an adult. During the hearing, the woman who survived the June 2025 attack also described what she saw.

The boy is charged with murder in the deaths of Christopher Hunnewell, 43, and Hunnewell’s adopted son, Ty Carter Hunnewell, 22. The Kennebec Journal is not yet naming the suspect because he is a juvenile.

Hugh Landry, a state police detective who led an evidence response team at the crime scene, testified that the Hunnewell home was in disarray when he and other investigators entered it. Walls and carpeting in the home were stained with red-brown spots, he said.

Landry, looking at photographs from the scene on Friday, identified the body of Christopher Hunnewell, with cut marks on his head and blood pooled underneath him. In the living room, where his body was found, police also found an ax, with red-brown stains on it later determined to be blood. They also found a fingerprint in the blood, which Landry said was later identified as belonging to the juvenile.

Landry said the marks on Christopher Hunnewell’s head were consistent with marks that would have been made by the ax.

Police also found a knife, also with red-browns stains on it, upstairs in the home.

Some of the several family members and friends of the victims cried during parts of Landry’s testimony.

Landry said he also spotted two security cameras, one in the kitchen and another on the mantle in the living room, that were plugged in but had been turned to face the walls. The teen’s fingerprints were found on at least one of the cameras, he said.

Police also found a journal, in what is believed to be the teenager’s makeshift bedroom, with hand-drawn comic-strip sketches depicting a deadly attack with an ax.

Bryce Scott, a state police trooper who was patrolling the area on June 11, 2025, said he responded around 8:40 p.m. to a report of an emergency where someone was injured or deceased in Chelsea.

When he arrived, he found the teen, in a black hoodie, pacing back and forth, and handcuffed him without incident. The trooper stayed with the teen as other police arrived, and rode with him to the hospital in an ambulance and remained with him at the hospital.

Scott testified the teen was visibly distressed and crying, stating to the trooper that, “Everybody was right about me.” The boy also stated he was a “monster” and asked to be killed, Scott said.

The teen is also accused of attacking Chili Mulgado, 23, now of Florida, who was Ty Carter Hunnewell’s fiancée and was living with the Hunnewells in June 2025.

Mulgado testified via video Friday that she and her fiancé were upstairs playing video games when the teen called from downstairs for Carter Hunnewell to come help Christopher Hunnewell, whose nickname was CJ, work on a mold problem in the home’s bathroom.

She said it seemed odd that the boy, and not CJ, would call upstairs, but she said he sounded very calm, so Carter Hunnewell went downstairs to help.

Mulgado said she was putting on her shoes to go downstairs, too, when she heard her financé scream, “Help me!”

She went downstairs and saw the teen stabbing Carter Hunnewell repeatedly.

Mulgado, who suffered serious injuries in the attack and was hospitalized, said she tried to stop the teen from stabbing Carter Hunnewell, grabbing the knife by its blade. The teen wouldn’t let go.

Their battle spilled outside onto a porch, then onto the ground. Mulgado was screaming for help: “I think he’s trying to kill me!”

She said she finally managed to get control of the knife, at which point she said the teen screamed, “Please don’t kill me!” and ran off. She went inside to call 911.

If the teen remains in the juvenile system, he could be sentenced to Long Creek Youth Development Center and released at age 21. If he’s tried as an adult and found guilty of murder, he could be sentenced to 25 years to life in prison.

Family members of the victims said Christopher Hunnewell and his wife, Jessie Carter, took in the teen — a relative — as a foster child after he had cycled through other foster homes.

Peter Schleck, director of the state Legislature’s Office of Program Evaluation and Government Accountability, attended the hearing to observe the proceedings. The Maine Legislature’s Government Oversight Committee previously ordered that office to investigate the Department of Health and Human Services’ involvement with the teen in the Chelsea killings.

Lawmakers said previously that they were troubled by reporting in the Press Herald detailing interactions the teen and his family had with DHHS’s Office of Child and Family Services. Carter told the Kennebec Journal that she and her husband had raised concerns with DHHS about the boy’s mental health and had sought another foster home for him.

The teen, who is slender and has long, shaggy black hair, attended the first two days of the hearings, but not Friday’s session.

One of his attorneys, Walter McKee, said juveniles are not required to attend such hearings and because Friday’s session was expected to be shorter, it didn’t make sense to bring him up from Long Creek in South Portland, where he’s being held.

District Court Judge Charles Dow, who presided over the three-day hearing, will make his decision on whether the teen will be charged as an adult after lawyers for both sides submit their closing arguments in writing. The process is expected to take at least a month.
