The Allegheny County Jail is on lockdown, Pittsburgh’s Action News 4 has learned.A jail spokesperson said that the lockdown began Friday as part of a full facility search.Brian Englert, president of the jail employees' union, said the lockdown began after reports of inmates overdosing."My understanding was there was two overdoses on Friday that were nonfatal on the morning shift and they brought in the police dogs in the afternoon shift to try to find any of these drugs, to get them out of the building," Englert said.Earlier this year, Action News Investigates reported overtime has soared at the jail because of a shortage of officers.Englert said the shortage makes it easier for drugs to be smuggled into the jail."The less people we have doing these jobs and the longer they are forced to work the hours, like 16-hour shifts, there may be things that get missed in the intake department, drugs or other contraband that make its way upstairs in the facility," Englert said.He said the Friday night shift was down 62 officers, or two-thirds of the total that should have been working."I mean, it's Hail Mary corrections. We're not following state procedures," he said.County Council member Bethany Hallam is on the jail oversight board."There are dozens of vacant medical staff positions, hundreds of vacant correction officer positions. They're operating a facility, I believe, very recklessly by not having the proper staff to accommodate how many people are in the jail," Hallam said.She and Englert said the shortage has continued even after the county dropped a residency requirement for corrections officers.A county spokesperson said the jail's primary concern is the safety and security of employees and inmates. The jail spokesperson says all in-person social and professional visitation remains on hold until further notice.
