A Scottsbluff woman is accused of assaulting a teenager, causing head injuries after she allegedly assaulted him with a bottle.

Marissa Sifuentes, 18, has been charged with second-degree assault, a Class IIA felony, and minor in possession, a Class III misdemeanor, stemming from a July 21 assault on a Lyman teen.

Nebraska State Patrol troopers investigated the assault, having been called to the hospital about a male who was being transported to Regional West Medical Center. The teen had been struck in the head, suffering from arterial bleeding, according to an arrest affidavit.

The teen told troopers that he had picked up five people, one of whom was Sifuentes and they had gone out to Lake Minatare. After they were done hanging out at the lake, he said, he was asked to give them a ride and he needed to get to his home by a 9 p.m. probation curfew. After noticing that he was going to be late for curfew, he said, he got into a verbal argument with Sifuentes and another passenger in the vehicle. The passenger had tried to pull his arm while he was driving, he told troopers, and the argument progressed until he stopped his vehicle and kicked his passengers out of the vehicle on South Morrill Road.

The teen said he and Sifuentes shoved and hit each other and as he was getting into his seat to leave, the woman struck him on the back of the head twice. He drove to his home and his guardian contacted police and had him transported to the hospital.

While officers were interviewing the teen, he received messages on Facebook, challenging him to meet another male in Morrill for a fight. Troopers responded to the message and waited for about 45 minutes, but the male never showed. The male messaged the teen again, telling him to meet him in Lyman. When troopers responded, they found multiple individuals in the residence and troopers questioned them. One witness told troopers a similar story to the teen, telling troopers that a verbal and physical altercation had occurred before the teen attempted to leave and Sifuentes struck him with a bottle.

Troopers and Scotts Bluff County Sheriff’s deputies made contact with Sifuentes, who was under the influence of alcohol. She tested for a .20 blood alcohol content level and was transported to Regional West Medical Center after she became unconscious.
