CLAY COUNTY, Fla. -

The fourth man arrested in connection with the theft and transfer of the gun used in the killing of Clay County Detective David White in February 2012 pleaded guilty Monday.

Curtis Dingler, 20, pleaded guilty to a charge of dealing in stolen property. He faces up to 15 years in prison.

Dingler also pleaded guilty to other charges unrelated to White's death, including one count of possession of ammunition by a convicted felon, one count of sale of cannabis and one count of possession of controlled substance paraphernalia.

He faces up to 40 years in prison on all of the charges. He will be sentenced Oct. 21.

Dingler's co-defendant, Curtis Henderson, pleaded guilty in June to a charge of dealing in stolen property and was sentenced to two years in prison. Two other co-defendants in the stolen gun case - Robert Apple II and Jack Lemond - pleaded guilty in May to a single count of dealing in stolen property. Both were sentenced to seven years in prison.

The gun was stolen in Jacksonville in May 2011. The weapon was provided to Ted Tilley, a convicted felon, who shot Detective White during a narcotics investigation last year.

Four individuals are charged in White's killing. Ryan Wilder, Chasity Prescott and Jennifer Alder are charged with first-degree murder, second-degree felony murder, three counts of second-degree attempted murder, and trafficking methamphetamine. Prescott also has an additional charge of burglary of a dwelling.

Jerry Daniels, a minor, is charged with third-degree murder and possession with intent to sell.
