The suspect, 31-year-old Jose de Jesus Montoya Villa, is wanted for first-degree murder, according to a news release from the Aurora Police Department.
A 36-year-old woman was killed and two were injured in a shootout during an event of about 15 to 20 people at the Iglesia Faro de Luz church, police said.
Police said on Saturday that the suspect knew at least one of the victims. He said he fled the church before the police arrived.
“It wasn’t just a random shooting inside this church,” Aurora Police spokesman Matthew Longshore told a news conference.
A reward of up to $2,000 is being offered to anyone providing information leading to the arrest of the suspect.
