The manhunt heats up for a suspect accused of killing a local Border Patrol Agent.  On Friday, the FBI and Customs and Border Protection introduced a $350,000 reward for the tipster who can lead them to Jesus Navarro Montes.  He's a suspect in the death of Yuma Sector Border Patrol Agent Luis Aguilar.

Border Patrol hopes the money and a promise of anonymity will urge people to come forward with information.

"They can rest assured that their name will not become public record, and there are many safeguards in place that will keep them from going on the public docket," says Agent Ben Vik.

On January 19th, Luis Aguilar was run over by a drug smuggling vehicle in the Imperial County Sand Dunes.  Agents say Montes fled back to Mexico after the attack.

"Our best lead is this suspect, and if we can get him into custody, I'm sure the Luis Aguilar family would rest."

In June, Montes was released from a Mexican prison after a judge cleared him of unrelated charges.  Mexican officials claim they never received documents requesting extradition to the United States.
