One party was discovered at 1:23 a.m. Oct. 25 at 416 Serpentine Drive, and the other occurred at 11:57 p.m. Oct. 10 inside 61 Youngwood Road, Lauth said.

Numerous citations for underage drinking, corruption of minors or furnishing alcohol to minors were issued.

"(Underage drinking parties) were declining over the past couple of years, until these two most recent incidents," Lauth said. "It's more what goes with it, as far as other things that can happen with juveniles getting intoxicated."

He said adults should be aware that even through the juveniles are drinking inside, other events can occur, such as assaults and alcohol poisoning.

The most recent incident on Serpentine Drive was reported through a state police liquor control board enforcement underage drinking hotline at 1-888-under21.

"Officers went to the house to investigate the complaint and, upon approaching the house, they heard a loud party coming from the garage," Lauth said.

Police looked through a window and saw a group of juveniles, who appeared to be under the age of 21, drinking beer.

The front door was opened to police by Gemma Brailey, 49, who lives in the house, Lauth said.

"They were invited into the house and it went from there. Mrs. Brailey admitted to providing beer for the minors," Lauth said. All of the minors were released to their parents.

Brailey was charged with corruption of minors and furnishing alcohol to minors. Charged with underage drinking were Evan Brailey, 18, of 416 Serpentine Drive, Luke Alberts, 18, of 837 Northridge Drive, Pittsburgh, Kyle Goodyear, 18, of 2 Forest Glen Drive, Mt. Lebanon, Tyler Graham, 18, of 800 Northridge Drive, Pittsburgh, Michael Greenberg, 18, of 975 Lindendale Drive, Mt. Lebanon, and Lauren Shaw, 18, of 234 Main Entrance Drive, Mt. Lebanon. Also cited for underage drinking were 10 boys all age 17, 13 girls age 17, and one 16-year-old girl.

Police received a call directly to the dispatch center of a possible underage drinking party Oct. 10 at 61 Youngwood Road, Lauth said.

"When officers arrived, they saw two younger looking males and a younger-looking female near the front port of the house," Lauth said. "As they walked up to the juveniles, they could smell the odor of alcohol coming from the juveniles. All three ran up the steps and into the house yelling 'cops,'" Lauth said.

A group of juveniles attempted to leave the house, with police apprehending some and others fleeing into the nearby woods.

Police found beer and various other alcohol beverages in the basement of the house. Marijuana residue and a marijuana cigarette were found in an ashtray near a dining room table on the first floor, Lauth said.

Owners Dr. Eric Nabors, an orthopedist, and his wife Marian Nabors, told police they were upstairs sleeping.

Their juvenile son was one who fled. He was contacted by cellular telephone and returned to the house, Lauth said.

Underage drinking citations were issued to two 17-year-old boys, five 16-year-old boys, and two girls, one 16 and the other 17 years old, Lauth said.

The adults, Eric and Marian Nabors, were charged with furnishing alcohol to minors, Lauth said, adding the investigation continues as to the owner or owners of the marijuana.

"While we have seen a decline in underage drinking arrests, what we have noticed is an increase in the (blood-alcohol) level when the kids are arrested," Lauth said. "Kids are drinking to higher levels of intoxication and that definitely leads to a fear of other kids of things happening."
