At least six people were killed and over 40 were injured in multiple mass shootings across the country during the Halloween weekend, according to officials.
In Texarkana, Texas, three people were killed and three others were injured at a party in a room at a business in the 700 block of N. Stateline Avenue around 9 p.m. Saturday.
"Apparently, this all started when a fist fight broke out between two men at the party. At some point during this fight, at least two men there pulled out rifles and started shooting," the Texarkana Texas Police Department said in a statement.
Six people ages 19 to 31 were shot. A man was pronounced dead at the scene, and a woman and another man died at a hospital overnight.
"The three other victims — two men and a woman — suffered what are not believed to be life threatening injuries and are recovering at the hospital," police said.
Detectives are searching for Breoskii Warren, 20, whom they've identified as a suspect in the shooting.
Texarkana police ask anyone with information about the shooting or Warren's whereabouts to come forward.
In Indianapolis, a woman was killed and eight other people were shot at a large party.
Indiana police officers responded to the party Sunday at around 12 a.m. to find shots being fired and people running, the police department said. More than 100 people were at the event.
The woman was pronounced dead at the scene. All of the victims are 16 to 22, police said.
