A Red Lion man must spend at least 15 years in prison for sexually abusing four children.
He was stopped when the mother of one of his victims became suspicious and set up hidden cameras in her home, police said.
Those cameras recorded Timothy Lee Grube molesting the woman's 2-year-old daughter in May 2013, and he was arrested, state police said.
Grube, 58, of South Franklin Street, pleaded guilty Thursday in York County Court to two counts each of involuntary deviate sexual intercourse with a child and aggravated indecent assault.
He was sentenced to 15 to 50 years in state prison as part of a negotiated plea agreement, defense attorney Clasina Houtman confirmed.
More victims: Two months after his arrest, troopers filed three more sets of child-molestation charges against Grube on behalf of three victims who subsequently came forward.
He sexually assaulted a girl for three years, starting in January 1991 when the girl was 12 years old, police said.
She said she told Grube to stop touching her, but he refused. So she alerted her family members in 1993 and they confronted Grube, who admitted he had sexually abused her, court documents state.
Cops not called: But no one from the girl's family went to authorities at the time, state police confirmed.
Grube also confessed to performing and receiving oral sex from a girl for a two-year period beginning in January 2009, when the girl was 6 years old.
The assaults happened in Grube's old apartment in the first block of East Boundary Avenue in Dallastown, documents state.
In December 2012, Grube forced a 6-year-old boy to perform oral sex on him at Grube's Franklin Street apartment in Red Lion, police said.
"He has expressed regret ... (for) hurting the children and hurting all of his family," Houtman said.
