A Baton Rouge man out on bail on state drug and firearm charges when he allegedly struck and killed a 12-year-old boy May 31 while fleeing from police was indicted on new drug charges Wednesday by a federal grand jury.

The federal drug and firearm charges brought against Joshual Hilton, 32, are unrelated to last month's incident that took the life of Samuel "Sammy" Lee III. Hilton claims he did not hit the boy.

Hilton's federal charges include distribution of methamphetamine and cocaine; possession with intent to distribute 500 grams or more of a substance containing methamphetamine, marijuana and promethazine; possession of a firearm by a convicted felon; and possession of a firearm in furtherance of a drug trafficking offense.

The charges stem from incidents that occurred in February 2015, and in January and September of last year, according to the five-count indictment.

The May 31 incident that claimed Sammy's life resulted in Baton Rouge police booking Hilton on counts of manslaughter, obstruction of justice, aggravated flight from an officer, and possession with intent to distribute Schedule II drugs.

Hilton also is scheduled to stand trial in state district court later this year on a host of drug and firearm charges, some of which stem from his Sept. 22 arrest on drug and firearm counts. The federal firearm charges revolve around that same arrest.

Chris Alexander, who is Hilton's attorney on the 2016 state drug and firearm charges, declined comment when told of the federal indictment. He said he had not seen the indictment.

Hilton also is accused of leading authorities on a high-speed chase on that September day when they tried to pull him over after allegedly witnessing what appeared to be several hand-to-hand drug transactions. An arrest report says he raced off at more than 100 mph down Old Hammond Highway in a red BMW M4 before abandoning the car on Holt Drive and running away on foot. He was caught less than a mile away.

Prior to May 31, Hilton was free on bails exceeding $400,000. East Baton Rouge Parish prosecutors are now asking state District Judge Chip Moore to revoke his bonds and hold him without bail until his state court trial on the 2016 drug and firearm charges. Hilton is scheduled to appear before Moore on Thursday.

Sammy, a fifth grader, was crossing Old Hammond Highway at Gloria Drive when Hilton's truck allegedly struck and killed him. Shortly before that, police say, Hilton threw large quantities of suspected crystal methamphetamine out the driver's side window of his Ford F-150.
