NEW YORK CITY — V. Reddy Kancharla, the former president of Testwell Laboratories, was convicted in 2010 of faking safety test results for the concrete being used in Yankee Stadium, One World Trade Center and other major New York City construction projects.
He was also a supporter of Council Speaker Christine Quinn's mayoral campaign after giving a $500 donation in October 2007. Quinn's campaign did not return the funds even though Kancharla was a convicted felon.
It was the only donation from Kancharla, was found guilty in February 2010 of falsifying business records and other charges, in the 2013 race, after giving thousands to Mark Green's failed mayoral bid in 2001.
During his trial, Kancharla tried twice to take his own life before being initially sentenced to 21 years in prison. An appeals court in 2012 overturned the most serious conviction of enterprise corruption. Kancharla has been released pending appeal.
"As is our campaign policy, donations from individuals convicted of a crime are returned," Quinn campaign spokesman Michael Morey wrote in a statement. "This small contribution is being returned as well."
Kancharla's lawyer declined to comment.
