Randy Lambach, 45, allegedly trolled the Pittsfield for potential victims for years,  one of whom may have been as young as 15, according to a witness.
The pimps kept most of the cash the escorts made and controlled the women by plying them with heroin, cocaine and prescription drugs, the Berkshire Eagle reported.
Cops started investigating in the spring of 2017 after they received complaints about an increase in prostitution in specific areas of the city.
They found that “Randy’ Lambach recruited at least 10 girls, found ‘dates’ for them on backpage.com and would drive them to and from appointments in his blue station wagon, and would sometimes keep an eye on proceedings from a closet or doorway.
Randy Lambach would seek out women with a drug addiction, photograph them and post advertisements online, seeking clients for sexual services, police were told.
Men would contact Lambach via cellphone and a date, time, location and fee would be agreed upon.
Rates were typically $80 for 30 minutes or between $160 and $200 for an hour.
Lambach would then contact the woman and drive her to the appointment, police said. He would sometimes wait outside or watch from a closet or doorway.

The master pimp, Lambach, organized and ran the entire prostitution operation

He would collect the cash and keep anywhere from 50 to 90 percent. Sometimes he would keep all of the entire fee and pay the woman with a few bags of heroin or some crack cocaine instead.
He also kept his girls in line, telling them no one would believe, if they went to police because they were “drug addicts and whores.”
Lambach allegedly threatened to turn the women in if they stopped working for him, and warned them the police would not believe, if they told on him they were, “drug addicts and whores.”
He also allegedly recruited his own foster daughters for his disgusting scheme.
Cops said Lambach drove the women to the residence of Joseph VanWert at a local senior living facility at least five times.
VanWert, 65, allegedly allowed Lambach to use his apartment as a meeting place in exchange for cash and drugs. However, he paid cash for sex with the women.
The depraved pair was arrested Nov. 14, and are being held without bail.
Appearing in Central Berkshire District Court court Tuesday, Lambach pled not guilty to four counts of human trafficking.
Van Wert pled not guilty to conspiracy to commit human trafficking and maintaining a house of prostitution, and and sexual conduct for a fee.
Cops said additional charges may be coming.
