Two Massachusetts men were busted for running a prostitution ring– that sometimes operated out of an old age home, cops said.

Randy Lambach, 45, allegedly trolled the Pittsfield for potential victims for years, keeping most of the cash they made and plying the women—one who may have been as young as 15– 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 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—sometimes watching from a closet or doorway, the paper reported.

Lambach allegedly kept anywhere from 50 to 90 percent of the cash, giving the girls drugs instead and telling them that no one would believe them if they went to police because 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.

The depraved pair was arrested Tuesday and is being held in Central Berkshire District Court without bail.

Lambach pleaded not guilty to four counts of human trafficking. Van Wert pleaded not guilty to conspiracy to commit human trafficking and maintaining a house of prostitution, among other charges.

Cops said additional charges may be coming.
