Federal officials say they're now offering a $55,000 reward for an arrest and conviction related to the 2007 shooting of a park ranger at a northern New Mexico lake.
The FBI and officials with the U.S. Army Corps of Engineers announced the reward at a news conference in Albuquerque on Friday. The FBI is pitching in $25,000 and the corps $30,000.
The shooting happened the morning of Dec. 1, 2007, after Park Ranger Alfred Chavez noticed someone had tampered with a lock and chain on a pump house gate near Abiquiu Lake.
Two men left the pump house as he was investigating. One of them pulled out a revolver and fired two shots. One of the bullets hit Chavez above the knee.
Chavez survived, but the men still have not been caught.
