A former landscaping company executive was sentenced Tuesday to probation — six months in a halfway house and six months of electronic monitoring — for his role in a $19.4 million fraud, kickback and money-laundering scheme that previously led to prison terms for four others associated with American Senior Communities.

Mainscape founder David Mazanowski was the fifth and last defendant in the case. He had agreed to plead guilty to one felony count of conspiracy to commit mail, wire and healthcare fraud in late 2016 after voluntarily resigning from his company.

Mazanowski’s sentence also included a $60,000 fine and an order to pay restitution of $808,000. He obtained almost $800,000 in the scheme, prosecutors said.

The 2009-to-2015 scheme, prosecutors said, involved secret side deals, inflated bills or bills for services that were never provided, and kickback payments that involved more than a dozen of ASC’s vendors as well as shell companies that would inflate vendors’ bills and submit them to ASC as if the shell companies were the real vendor.

Former ASC CEO James Burkhart, whom prosecutors said led the scheme, was sentenced June 29 to 9 1/2 years in prison and three years of supervised release. Former COO Daniel Benson was sentenced Friday to 4 1/2 years in prison for his role.

Steven Ganote, described as a friend and associate of former ASC CEO James Burkhart, received a five-year prison sentence on Monday. Also that day, Joshua Burkhart, brother of the former CEO, received a sentence of four months plus two years of supervised release, the first eight months during which he will be electronically monitored.
