Correction to an earlier version of this story: Johnson and Smith pleaded not guilty in February.

MEMPHIS, Tenn. — One of the suspects charged in connection with Young Dolph’s murder, Justin Johnson, was involved in an incident in jail Friday, according to the Shelby County Sheriff’s Office.

TMZ reported Johnson, also known as Straight Drop, was punched by another inmate at 201 Poplar while in the middle of a phone call, according to his attorney.

A Shelby County Sheriff’s Office spokesman called the incident an “attempted fight.”

SCSO said there were no injuries, and the incident was still under investigation.

Johnson, 23, was arrested on Jan. 11 for the murder of Memphis rapper Young Dolph.

Johnson and another suspect, Cornelius Smith, both pleaded not guilty in February.

Their next hearing is set for March 24.
