Despite an extensive investigation by the Yuma Police Department and other agencies, which has included conducting over 1,300 interviews and fielding hundreds of tip calls, the perpetrator of this mass murder has not been apprehended.

Witnesses described a Hispanic male entering the residence following the shooting. Based on eyewitness accounts, police were able to put together a sketch of the suspect. According to authorities, two persons close to Luis Rios have not been cooperative in the investigation. Police are encouraging those who had called anonymously with tips before to call again. Below is a list of the information Yuma Police are seeking from the public:
