“I wanted to make the judge understand that this person is a community predator,” Langerman said outside the courtroom.
“I'd like him taken off the street so he doesn't do this to anyone else.”
Several alleged victims who testified said they met Sanders at youth sporting events or church, where he proposed landscaping business deals with lucrative returns.
Many have sued Sanders in civil court for breach of contract, and some, like Oklahoma City attorney Kelly George, have won judgments against him.
“I've never met anybody quite like him,” said George, who won a $3,500 judgment against Sanders in 2008. “He's nice. You want to help him.”
Adams called Sanders “the biggest con man in the history of the universe.”
The attorney said he was victimized by Sanders, who was hired to install a gate at his Edmond home. Adams estimates Sanders was paid in excess of $30,000 for work that was never completed.
“He's been ripping off people for a long time,” said Prater, who hired Sanders to do some landscaping at his house in 2008.
“They did part of the work and then disappeared,” he said.
“I shouldn't have paid them in advance.”
Prater said Friday he is not involved in prosecuting Sanders.
Former Sooner basketball star Eduardo Najera and his wife won a $232,763 judgment against the landscaper's business in August 2008 after no one responded to their lawsuit.
Prosecutors charged Sanders with perjury in 2010 after he lied in court about a prior conviction.
He pleaded guilty to arson in 2004 in Texas.
In the other case before Watson, Sanders deposited a bad check for $1,400 and received $700 back, records show.
