KANSAS CITY, Kan. (AP) — The hunt continues for a second suspect in a weekend Kansas bar shooting that left four dead and five wounded after officers searched two homes in the area without finding the fugitive.

The Kansas City Star reports that police looked Tuesday for 29-year-old Hugo Villanueva-Morales first at a duplex that’s less than 1 mile (1.61 kilometer) away from the Tequila KC bar.

Gunfire erupted at the bar early Sunday about two hours after Villanueva-Morales got into an argument and was forced to leave. Police Officer Jonathon Westbrook says police also searched a second home before determining Villanueva-Morales wasn’t there.

Villanueva-Morales and 23-year-old Javier Alatorre are charged with four counts of first-degree murder. Alatorre was arrested Sunday in Kansas City, Missouri. Police say Villanueva-Morales should be considered “armed and dangerous.”
