A Butler County judge granted a couple weeks grace to a city man who is about to do state prison time for operating a volatile mobile meth lab.

Kenneth Roberson, 59, has until Dec. 14 to find out if his prostrate problems are caused by cancer, then report to prison.

But Roberson’s request to postpone sentencing on his 2- to 6-year jail sentence while his yet undiagnosed medical condition is treated was thwarted by his recent address: A Wagner Avenue home that’s been the sight of recent drug arrests and a shooting.

“His health issues haven’t prevented him from being involved in drug activity in the city,” argued county Assistant District Attorney Mark Lope, who wanted Roberson to go to prison immediately. “He’s trying to manipulate the court with his condition and his status as a veteran.”

Roberson, whose criminal record spans three states during more than 30 years, claimed he was unaware there was drug activity in the home and moved as soon as he found out.

Lope retorted that Roberson’s denial of awareness was the same defense he’d initially presented in the meth lab case.

Roberson was charged in that case after city police got a tip about a potential meth lab at a home in the 200 block of Roosevelt Boulevard.

The occupant of that home reported there was a duffel bag in his driveway, laying against the house. The bag, documents said, was “smoking.” Police got there and found the bag, which contained plastic bottles.

A closer look confirmed the contraption was a mobile meth lab, which authorities suspect had been moved from a Liberty Street house where Roberson reportedly had been living with James Webb and his then-girlfriend, Brianna Adkins.

Because the contraption was potentially explosive, the Butler County Hazardous Material Teams and Butler Fire Department were called and helped police set up a safety perimeter around the Roosevelt Boulevard home. The duffel bag was removed and the lab was dismantled.

Adkins, 29, of Canton, Ohio, pleaded guilty to possession of a controlled substance and reckless endangerment. In September, she was sentenced to serve 2 years’ probation.

Webb, 32, of Butler pleaded guilty to conspiracy, and in May he was sentenced to serve 3 to 6 years in prison.

Roberson pleaded guilty to two felonies: possessing red phosphorus with intent to manufacture a controlled substance and risking a catastrophe.

In an unrelated case, he also pleaded guilty to possession of a controlled substance.

In exchange for Roberson’s plea in both cases, the prosecution dropped additional charges and recommended the state prison sentence.

During the sentencing hearing, Roberson told county Judge Timothy McCune that he’s prepared to serve his state sentence, but he first wants to be tested for cancer and treated at the Veteran’s Administration in Pittsburgh.

He claimed that because of his medical issues he was unable to leave the couch on the first floor of the Wagner Avenue home and therefore had no knowledge of activities elsewhere in the house.

“None of those things that went down had Kenneth Roberson’s name on it,” he said, alleging he moved to a different Wagner Avenue home as soon as he learned of the activities.

Although Roberson has no recent charges, Lope noted that Roberson is named as present and having involvement with police during the arrest of a different drug suspect at the house on Nov. 21.

The judge declined to postpone Roberson’s sentencing. However, the judge ordered Roberson to report to prison a few days after he is reportedly scheduled for a biopsy.

“The state (prison) can take care of your medical condition,” McCune said.
