There will be a lockdown in security beginning Monday at the U.S. District Courthouse in downtown Columbus, as jury selection begins in the trial for five former members of the so-called Short North Posse. According to a judge order issued late January, courthouse officials worried about “heightened security concerns” in the upcoming gang trial.

In the court order, U.S. Marshals indicated each defendant would be leg bound during trial and officers would be equipped with machinery like stun guns. Judge Algenon L. Marbley’s order also called for a second security checkpoint where officers would detain cell phones and review photo IDs. There will also be assigned seating based on relationship to the defendants.

The gang members on trial were affiliated with the Posse’s “Homicide Squad,” and are accused of killing at minimal 11 people.

Rashad “Buckwheat” Liston, 26; Robert “Killer B” Ledbetter, 37; Christopher “O-Dog” Harris, 28; Deounte “D-Frog” Ussury, 31; and Clifford “Tink” Robinson, 38, will face trial on Monday.

The U.S. Attorney’s Office says the Short North Posse terrorized central Ohio for 30 years.

In 2013, Federal authorities and Columbus Police arrested 22 people with connections to the violent gang. A year later, prosecutors unleashed the largest federal murder indictment in Ohio history when they linked 17 members to 14 murders.

U.S. marshals and armed guards will reportedly patrol the in and around the courthouse as well.

Reportedly, the trial is expected to last three months. Meantime, five more Short North Posse members will face trial later this year.
