The Federal Bureau of Investigation is offering a reward of up to $20,000 for information leading to the arrest of Alejandro Aguilar.
Aguilar is wanted for alleged involvement in the shooting of four men, killing two on October 9, 2009 in Shafter, CA.
An arrest warrant was issued October 10, 2009 after he was charged with two counts of first degree murder and two counts of attempted murder.
A federal arrest warrant was issued on May 18, 2010 after he was charged with unlawful flight to avoid prosecution.
Anyone with information is asked to contact the local FBI office or nearest American Embassy. Authorities think he may have fled to Mexico.
Aguilar is described as a male approximately 5'5" to 5'6" and 120 to 130 pounds. He has a tattoo on his forearm and should be considered armed and dangerous.
