LEE COUNTY, Fla. - One of six suspects in a double murder in Bonita Springs will not go to trial.

Robert Patrick Downey reached a plea deal with prosecutors. He pleaded guilty to accessory to murder. He admitted to helping clean up the murder scene.

He faces 15 years in prison, but he's agreed to testify against the other suspects which could bring him a lighter sentence.

The men are accused of beating two men, suffocating them, and torching the car to get rid of the bodies.
