BALTIMORE — An alleged gunman accused of taking part in a deadly mass shooting at last year's Brooklyn Day celebration was stabbed multiple times while awaiting trial in prison.
The Maryland Department of Correctional Services confirmed Tristan Jackson was assaulted during a June 6 altercation with another inmate.
Jackson was treated at an area medical facility for non-life threatening injuries.
In a statement the department said it's investigating the stabbing and reviewing Jackson's medical care.
"The department's Chief Medical Doctor has begun a thorough review of Jackson’s medical care," the department wrote in an email to WMAR-2 News. "There is no indication of Jackson having missed any of his medication or a medical appointment."
According to prosecutors, Jackson was caught on surveillance footage shooting at a large crowd inside the Brooklyn Homes.
He was also on GPS monitoring at the time for an unrelated matter, which placed him at the shooting scene.
