They are described by Brownsville police as armed and dangerous. Twenty-nine year old Roberto de Luna Magallon and 31 year old Gilberto Preciado-Franco, of Nuevo Laredo, are wanted by police, each charged with two counts of murder.
Back on September 30th a Cameron County Sheriff's Deputy found a truck off of FM 511 riddled with bullet holes and two dead men inside, the victims, 38 year old Guadalupe Perez Chavez and 25 year old Omar Castillo Flores.
"These are individuals that were contracted or hired for a certain purpose and that was to kill one of the brothers of Beto Fabe, in this case we're talking about Omar Castillo." said Brownsville Police Chief Carlos Garcia.
Garcia adds that Fabe, who was head of the Gulf Cartel in Matamoros, got into some trouble with the organization a few months back and was killed. Since then, the cartel has been after his family and Omar Castillo was next on the list.
As investigators worked tirelessly, a few pieces of key evidence surfaced.
Police found the get-away truck abandoned across town, and what they found next would lead them to a name of one of the killers.
"Our crime scene people were able to process that vehicle and retrieve fingerprints that lead us to the identification of one of the shooters." said Chief Garcia.
Once they had one name, police say other information started falling into place and authorities were able to name the accomplice.
On November 3rd arrest warrants were issued for the two men and on the 10th authorities executed search warrants in several cities throughout Hidalgo County, in San Antonio and in Detriot,MI.
The searches were unsuccessful, Preciado-Franco and de Luna-Magallon remain on the run; authorities believe they may have fled back to Mexico.
If you have any information on their whereabouts, you are urged to contact Brownsville Crime Stoppers, your tip will will remain anonymous, that number is 546-TIPS.
