Sunday’s homicide of a Utica teenager is a case of domestic violence, not cyber stalking as internet rumors alleged this week, according to Oneida County District Attorney Scott McNamara.

21-year-old Brandon Clark is accused of killing his girlfriend, 17-year-old Bianca Devins, by stabbing her. He posted images online, which then gained national attention and led to the spread of unsubstantiated rumors.

Clark is charged with second-degree murder.

Police say Devins was killed by Clark on Sunday morning, causing a delay of the Boilermaker. Police said they had attended a concert at a New York City bar together over the weekend.

McNamara says his office is working closely with the venue to get answers about what happened at the event, including going through surveillance video.

He says there are rumors going around about Clark being an "incel”, but McNamara emphasized he believes this was a domestic violence case.

"First time I've ever heard of [incel subculture],” said McNamara. “There's supposedly a group of men that dislike women and have celibacy, and we don't have any evidence of that."

Spectrum News has also learned about an incident from the past involving the suspect's father, Jason Clark. He was involved in a standoff with police following a domestic call in 2010. During the incident, authorities say he held a steak knife to a woman's throat, cutting her.

Memorial services for a 17-year-old girl killed in Utica on Sunday have been announced.

The public wake for Bianca Devins, who was allegedly killed by 21-year-old Brandon Andrew Clark, will take place Thursady, July 18 from 4:00 p.m. to 7:00 p.m. The public funeral for Devins will take place on Friday, July 19 at 1:00 p.m.

Both the wake and funeral will take place at the Church of Our Lady Lourdes in Utica.

Devins was a graduate from T.R. Proctor High School and was set to attend Mohawk Valley Community College in the fall.

"Our family is devastated by the loss of our beautiful angel, Bianca,” said Kimberly Devins, Bianca’s mother. “Our lives are now forever changed; our hearts are broken. My heart is completely shattered, having lost my best friend. We will always remember her beautiful smile that lit up our lives. Her spirit will strengthen us and live on forever.”

Bianca's family has set up a scholarship fund in her name, which is in the care of the Community Foundation of Herkimer and Oneida Counties.
