More than 200 stamp bags of suspected heroin and baggies of marijuana were seized from a Butler home in a Thursday night raid by Butler County drugs officers and city police, authorities said.

Officers arrested three people including a Pittsburgh man who was using the house in the 100 block of Fourth Avenue as his drug-selling operation, said task force supervisor and county Detective Tim Fennell this morning.

Investigators had long suspected drug activity at the three-story home and recently had done several controlled heroin buys there, Fennell said.

Authorities later got a search warrant that was served at the house shortly after 9:30 p.m. Thursday.

Inside, officers found six people, one a minor.

The listed occupant, Michelle L. Voelker, 37, was on the first floor. A search of her purse turned up 10 bags of heroin, 5.1 grams of marijuana, a digital scale and $232, according to court documents.

On the top floor officers found Nathaniel E. Jackson Jr., 28, of Pittsburgh and 177 bags of heroin, 11.6 grams of marijuana and $1,555 in currency, investigators said.

Officers arrested Jackson, Voelker and Mark S. Owens 36, of Lyndora, who was on the first floor with 27 bags of suspected heroin.

Voelker later admitted to investigators that she and Jackson had been selling heroin at the home, document said.

All three defendants are charged with felony and misdemeanor drug possession. They are all in the county prison.

Jackson is jailed on $100,000 bail, Voelker on $50,000 bail and Owens on $20,000 bail.
