Three people connected to a man who was found shot to death in his Warren County home have been sentenced to federal prison for drug trafficking charges.

Jack Huck, 23, of Ste. Genevieve, was sentenced this month to more than seven years in prison for his alleged role as leader of an organization that trafficked marijuana from the West Coast to Missouri, according to the U.S. Attorney’s Office for the Eastern District of Missouri.

Among almost a dozen co-defendants, Seth Ault, of Silva, and Dakota McCain, of Marquand, were sentenced to 36 months and 32 months in federal prison, respectively.

The three men are accused of assaulting and robbing Warrenton-area resident Airk Rader in August 2017. According to the Warren County Sheriff’s Department, the robbery was intended to recover payment Rader allegedly owed the men for marijuana. The three men allegedly broke into Rader’s residence armed with a tire iron and a pipe.

The robbery was stopped by the arrival of Rader’s roommate with a handgun, authorities said.

Over a month later, on Sept. 27, 2017, the 21-year-old Rader was found shot to death at his home on Township Line Road.

All three drug trafficking suspects, along with a fourth person, Ashton Roach of Fredericktown, were charged in Warren County with assault, attempted robbery, burglary and armed criminal action related to the August 2017 attack. Authorities at the time declined to say if any of them were also implicated in the second attack that killed Rader.

Roach — the only one of the assault suspects not included in the federal drug convictions ­— had a jury trial scheduled to begin this week in Warren County Circuit Court. The other three do not yet have proceedings scheduled here.

No homicide charges have been issued in connection to Rader’s death.
