SLIPPERY ROCK — Another Slippery Rock University homecoming weekend came and went with the traditional fare — the crowning of royalty, a parade, tailgating, football and alcohol-related arrests.

Most of the incidents were relatively minor but in one case a trooper was injured during an altercation with teenager who allegedly had too much to drink.

State police arrested Jacob Helman, 18, of Springdale, Allegheny County, after troopers from the Butler and Kittanning stations were called about 10:25 p.m. Saturday to help with several overzealous homecoming celebrations.

Police said they noticed Helman walking unsteadily on Kiester Road just east of Harmony Road in Slippery Rock Township, according to court documents.

When the teen nearly stumbled into the back of a cruiser, troopers got out to check on his condition. He promptly ran up the hill but was quickly caught. Police said they immediately suspected he was intoxicated.

A portable breath test measured Helman’s blood-alcohol level at 0.190 percent, more than twice the state’s 0.08 percent legal limit for drivers, police said.

The suspect was taken to the SRU police station where he “became very belligerent and started to become verbally and physically aggressive” toward two troopers, documents said.

Police said they eventually had to subdue Helman, Trooper Greg Bogan suffered a minor back injury in the altercation.

District Judge Dave Kovach arraigned Helman on charges of resisting arrest, disorderly conduct and underage drinking. He was placed in the Butler County Prison on $5,000 bail, following arraignment.

Also Saturday, police about 10 p.m. stopped Jacob J. Spangler, 20, of Pittsburgh driving a car on Vineyard Circle in Slippery Rock Township. He was found with a half case of beer.

Following an investigation, the officers determined he “did not consume enough to be arrested for (driving under the influence),” according to a police report.

Still, police said they cited Spangler for underage drinking and driving a vehicle with alcohol in his system.

Less than three hours later, police nabbed another young man while troopers were shutting down a large and loud party at The Heights apartment complex in Slippery Rock Township about 12:45 a.m. Sunday.

Police said they cited 20-year-old Alente H. Johnson of Rochester, Beaver County, for underage drinking after determining he had consumed “a fair amount of alcohol.”
