SHELTON, Conn. (WTNH) – The teen accused of fatally stabbing a 17-year-old in Shelton has been identified by his attorney on Thursday.

Attorney Jake Donovan said 16-year-old Raul “Lito” Valle of Milford turned himself into police early Wednesday morning. Valle is charged with murder and three counts of first-degree assault in the death of 17-year-old James McGrath of Shelton.

Valle, a St. Joseph’s High School student, was arraigned in New Haven juvenile court on Wednesday but is now being charged as an adult and was transferred to adult court in Derby, where he faced a judge on Thursday morning.

“Obviously, this is an unspeakable tragedy for everyone involved,” Donovan said.

Donovan spoke briefly outside of court on Thursday.

“It would be irresponsible for me to make a comment before I had a chance to examine all the evidence in this case,” Donovan said.

According to court documents, officers responded to a house party on Laurel Glen Drive in Shelton on Saturday night where police found over 50 teens at a house party. Officers located four separate victims on the front lawn of the home.

One of the stabbing victims told police he stopped by a party on Lazy Brook Road in Shelton with a friend and, “When they arrived, they encountered a group of guys that became argumentative with him.”

The victim went on to say, “He squared off with one of the kids and began fighting in the yard,” then, “…other kids jumped on top of him and began to hit him.”

The victim says he was able to get away and went to the house on Laurel Glen Drive where a different party was being held.

The warrant said multiple witnesses reported that three or four people who were not invited to the party arrived and got out of a Honda SUV. The witnesses told police the people in the Honda were from St. Joseph’s High School in Trumbull.

Another one of the victims told police, “He approached the group of kids and asked them to leave, but they refused, One of the two kids threw a punch at their group and a big fight broke out.”

The court documents said that when the people got out of the car, a physical altercation ensued on the front lawn. During the altercation, at least one suspect had a knife.

That’s when police said McGrath and three other victims were stabbed. McGrath was brought to Bridgeport Hospital, where he was pronounced dead.

The three other victims were treated for stab wounds.

Witnesses told police that Valle started a fight and witnesses reported seeing Valle with a knife that was described as a switchblade.

The court documents stated that autopsy results revealed that McGrath was stabbed in the chest. His cause of death was ruled “stab wound to the torso” and the manner of death was ruled a homicide.

Following the court appearance, the teen’s father said, “I’m sorry,” when leaving the court.

Valle is being held on a $2 million bond. He will be in Milford court on June 7.
