Washington, DC Ė The U.S. Marshals Great Lakes Regional Fugitive Task Force (GLRFTF) is seeking the publicís help in apprehending a man wanted for a 1998 murder in East Chicago, Indiana.

Javier OropesaJavier Oropesa (aka Guillermo Lanteros-Serna) is alleged to have shot Alexander Martinez in the face and head on Jan. 11, 1998, in the 400 block of Grove Street.

Oropesa, who is 48 or 49, was charged with the murder in February 2009, and the U.S. Marshals Great Lakes Regional Fugitive Task Force was requested to assist in the fugitive investigation.

GLRFTF Investigators obtained fingerprints from a 1997 Lake County, Indiana, arrest of Oropesa. Those fingerprints were submitted to the Department of Homeland Security.

He has ties to Northern Indiana, Southern California, and Mexico.
