ST. CHARLES COUNTY • Police are searching for a homicide suspect accused of breaking into a home here Sunday and fatally shooting a man. 

Police released a photo Friday of Irian Ochoa-Valdez, 29, of the 800 block of Lightwood Drive in Hazelwood. 

Ochoa-Valdez was charged with first-degree murder in the killing of Alberto Zayola, 29, on Jamaica Drive. Court documents said the killing was “due to a romantic relationship and infidelity,” but did not give more detail about the potential motive.

Police said Ochoa-Valdez and an accomplice, Eulices Cervantes-Salmeron, shot Zayola, took his body to Overland and dumped it in the back yard of a vacant home. Cervantes-Salmeron, 20, was charged with first-degree murder and was being held in the St. Charles County Jail Friday night with bail set at $1 million. 

A court document filed by St. Charles County police Tuesday said Valdez was deported from the United States in 2014 for a violent crime and "again has unlawfully re-entered the country." His home country wasn't cited.  

Police said Ochoa-Valdez should be considered armed and dangerous.

Officials ask anyone with information to call 911 or the St. Charles County Police Department at 636-949-3000.
