On January 10, 2024, at about 10:28 p.m., deputies answered a reported shooting in the 5600 block of Wakita Drive in rural Edinburg, Texas. Responding officers found 23-year-old Michael Daniel Arevalo unresponsive with multiple gunshot wounds; he was pronounced dead at the scene. Witnesses said two men in dark clothing and hoodies walked along the street and opened fire.

Investigators identified one suspect as 22-year-old Mario Cordero Jr., who was arrested on January 17, 2024, near the 700 block of East Iowa Road in Edinburg and charged with murder; bond was set at $2 million. A second person of interest, 24-year-old Efrain Keefer Tenopala, affiliated with the Sureno 13 Street Gang, remained at large as of January 18, 2024. Authorities say a social media dispute preceded the shooting; an incarcerated individual named Abel AJ Sanchez Jr. had given Cordero access to his Facebook account, which Cordero used to boast about the shooting in a private group chat.

Anyone who knew Michael, saw activity on Wakita Drive that night, or has information about Tenopala or the incident is asked to contact the Hidalgo County Sheriff’s Office or Crime Stoppers.
