State police scored a kind of DUI trifecta Sunday.

While on their way to the hospital to give one suspected drunken driver in Slippery Rock Township a blood test, troopers came upon a second one in Center Township.

Later, police said, a teenager showed up intoxicated at Butler Memorial Hospital in Butler Township to pick up the first suspect. That was arrest No. 3.

The unusual night began shortly after midnight when police say they pulled over Terel D. Lewis, 18, of Monroeville, Allegheny County for a traffic violation on Harmony Road in Slippery Rock Township.

The troopers arrested Lewis on suspicion of DUI, placed him in their patrol car and headed to the Butler hospital for a blood test. But before they got there, they spotted an erratic driver on Route 8 in Center Township.

That driver, David Robinette, 27, of Arkansas, was pulled over and he soon joined Lewis in the police car for suspected DUI.

Around 2:30 a.m. at the hospital, police said, Dylan R. Pierce, 18, of Monroeville, showed up there, presumably to give Lewis a ride home.

Investigators believe Pierce, still under the influence, had driven to the hospital from Slippery Rock.

A full report will appear in the Butler Eagle.
