A 'monster' pedophile, 70, who molested at least seven girls was sentenced to up to 50 years in prison on Thursday. Jackson County Chief Circuit Judge Thomas Wilson told 'monster' James Tingley of Michigan 'the only money we should waste on you is the cost of a bullet.' Wilson continued by saying he thinks locking Tingley up for the next 25 to 50 years in prison 'is worth every penny.' Scroll down for video .

They won't have to go through the victimization that the victims went through here,' Wilson told Tingley. 'Mr. Tingley, basically you are a monster who has destroyed the innocence of numerous children.' Mlive reports that James Tingley was convicted on March 3 of heinous sex crimes against two girls over a six year period. His crimes span a period of 50 years. During Tingley's hearing, Assistant Prosecutor Jennifer Walker told the court that police know of at least five other girls Tingley abused but they believe there may be more. 'The defendant, he has called himself "Jim", He has called himself "Uncle Jim" but I would call him a monster and a pedophile,' Walker said. Repeat offender: James Tingley, pictured on Thursday in court,  sexually abused at least seven girls, investigators said . 'The defendant has stolen the souls, or parts of the souls, of these children. He's used them to meet all of his sexual needs. ... He's been violent with them, with others he's treated them as a girlfriend and he's wanted them to be his wife. ... It's disgusting,' walker added. Timgley's attorney Eric White told the court that Tingley still claims he is innocent. White added that Tingley's health is declining and that it's unlikely he'll live past his first parole date which is when he turns 96. Tingley did not wish to say anything to the court. Prosecutor Jerry Jarzynka said he thought Tingley received a fair sentence for his cruel actions. 'Certainly when it comes to cases of criminal sexual conduct with minors we appreciate the judge handing out a stiff sentence and ultimately we want to protect our kids,' Jarzynka said. Mlive reports that Tingley's perverted accomplice Randy Stevens, 45, was also convicted of sexual misconduct by a separate jury for 'allowing Tingley to carry out a number of sexual assaults.' This is not the first time Stevens has been accused of aiding in child abuse. Stevens, a father of 14,  pleaded guilty to second-degree child abuse and a judge sentenced him six to 10 years in prison last year. Mlive reports that last year's conviction was related to Stevens letting his children visit another sex offender, Geoffrey Friant, who is now serving 30 to 80 years behind bars. Stevens will be sentenced on April 16. Both he and his wife, Bobbi Jo Stevens, have lost their parental rights to their children.
