AUSTIN -

The reward for Javier Cortez, Jr., 32, a Texas "10 Most Wanted" fugitive and this month's featured fugitive, has increased to $15,000 for information leading to his capture if the tip comes during the month of July.

Investigators believe the Tango Blast gang member wanted for murder may be living in Matamoros, Mexico, under an assumed name. Investigators are currently working to ascertain what aliases Cortez may be using.

If a tipster provides information that leads to an arrest, the reward will be paid, even if he is captured in Mexico.

Cortez is 5 feet 5 inches tall and weighs 142 pounds. He has previously been seen in Wharton County in the El Campo area, including Danevang. His last known address was in Pasadena, where he has family and children living in the area.

The 2010 Harris County murder charge stems from a robbery in which an accomplice shot the 29-year-old victim twice, and Cortez allegedly stood over the victim and shot him nine more times. The accomplice has been arrested, but Cortez has eluded capture.

He is also wanted for unlawful flight to avoid prosecution by federal authorities in addition to the homicide warrant.
