Affidavit: Argument led to double homicide in Alton

A probable cause affidavit for the arrest of a 22-year-old Alton man accused of killing two men states that an argument between the group led to the shooting.

The Alton Police Department arrested Oscar Armando Velasquez on Nov. 17 at the Hidalgo-Reynosa International Bridge.

The man is accused of shooting and killing 34-year-old Carlos Perez and 25-year-old Eduardo Rodriguez in the 900 block of Jefferson Street in Alton.

Alton Police Chief Jonathan B. Flores has declined to provide information on what motivated the shooting, citing the ongoing investigation, though he did describe the incident as a domestic dispute.

The probable cause affidavit doesn’t provide much new information, other than that Velasquez is accused of shooting Perez, Rodriguez and 30-year-old Matthew Compean, who survived, due to an argument.

Police discovered Perez and Rodriguez unresponsive with gunshot wounds at 8:45 p.m. on Nov. 8, the probable cause affidavit read.

That document alleges Velasquez used a handgun with a silver slide in the shooting before fleeing the scene in a white Honda CRV.

Velasquez remains jailed on $2.5 million in bonds on charges of capital murder of multiple persons and three counts of criminal attempt murder.
