Tucson investigators are looking for a Mexican man suspected of killing an ice cream vendor.

Police have obtained an arrest warrant for 19-year-old Felix Gaxiola-Flores, who has been returned to Mexico more than a dozen times for being here illegally.

Tucson homicide detective Fabian Pacheco says he now faces charges of first-degree murder and armed robbery.

Gaxiola-Flores is suspected of shooting the 29-year-old Cosme Encinas-Valenzuela in July in front of several witnesses, some of them children.

While investigators initially thought the robbery was tied to drugs, Pacheco says that is no longer the case.
