KANSAS CITY, Kan. (AP) — A suspect in a Kansas bar shooting that left four dead and five wounded remains on the lam, and authorities are urging witnesses to come forward amid the ongoing manhunt .

Police continued searching Thursday for 29-year-old Hugo Villanueva-Morales, more than four days after gunfire erupted early Sunday at the Tequila KC bar in Kansas City, Kansas. Villanueva-Morales and 23-year-old Javier Alatorre are charged with four counts of first-degree murder. Alatorre was arrested hours after the shooting at a home in Kansas City, Missouri.

Alatorre had his first court appearance Thursday in Wyandotte County District Court in Kansas to hear the charges against him, and another hearing was set for Oct. 15. The court clerk's office said he does not yet have an attorney.

Officer Thomas Tomasic says officers don't know whether Villanueva-Morales has left the area. He says police are at a "slow point right now as far as information." Police want to talk to any witnesses who were in the bar but left before officers arrived.
