Police raided an Evans City home Thursday that housed a marijuana grow operation and seized about $400,000 worth of drugs.

Authorities said their nine-month investigation began when neighbors complained of the smell coming from Curtis Chritzman’s home.

According to police, officials seized more than 100 pounds of marijuana -- 129 live plants, 17 large boxes filled with marijuana -- 34 fluorescent lights, books on how to grow marijuana and 12 guns.

Along with Chritzman, Brenhan Skrak was also arrested. Investigators called the two big-time suppliers in the area.

“We know we were finding their product at Westminster and in local townships being sold to kids and adults,” District Attorney Joshua Lamancusa said. “The marijuana was being sold on the street for $4,000 per pound. So that’s roughly $400,000.”

New Castle Chief of Police Robert Salem said authorities are still searching surrounding areas for more marijuana.

“There are investigators searching fields in Lawrence, Butler and Mercer counties with the help of a helicopter,” Salem said.

Detectives said they think Skrak and Chritzman have been in business for years.

They’re both being held in the Lawrence County Jail on dozens of felony drug charges.
