Following an investigation into the stabbings, police obtained a warrant for the arrest of Mendez-Sanchez. On Saturday about 6:30 p.m., officers visited his home and spoke to his mother, who said he was not there but that she would contact him and bring him to the police station.
According to a police report, Mendez-Sanchez arrived at the station at about 8:15 p.m. and was arrested. Mendez-Sanchez told police he arrived at the party alone and saw two people fighting over a girl. He said he was pushed outside and that a hooded man threw a machete, which he picked up and then was rushed by people with Tasers. He said he then fell to the ground and threw the machete. Police asked Mendez-Sanchez about his Facebook page and references to his being a Trinitarios gang member. He said he was a member of that gang in the Dominican Republic, but not here. Mendez-Sanchez denied hitting anyone with a machete, police said.
