Edwin Ernesto Rivera Gracias was added to the FBI's "Ten Most Wanted Fugitives" list on Thursday, March 14, 2013.

(CBS/AP) DENVER - Edwin Ernesto Rivera Gracias, a suspected member of a notorious Salvadoran gang and suspect in a Colo. slaying, is now one of the FBI's "Ten Most Wanted Fugitives."

The addition was made Thursday, on the 63rd anniversary of the creation of the list.

Rivera Gracias is wanted in Jefferson County, Colo. for the Aug. 17 stabbing death of 69-year-old Richard Limon of Denver, a family acquaintance of his girlfriend.

Three other suspects have already been apprehended.

Rivera Gracias is suspected of being a member of the Mara Salvatrucha gang, or MS-13, with ties to other gang members in Colorado, Los Angeles and El Salvador. He is believed to be hiding in El Salvador. The FBI is offering a $100,000 reward for information leading to his arrest.

The vacancy on the "Ten Most Wanted" list was created when Joe Luis Saenz, a murder suspect, was captured in November in Guadalajara, Mexico, after evading authorities for 14 years.
