HARRISBURG — Former state House Democratic whip Mike Veon was convicted today on 10 counts of theft, conspiracy and conflict of interest charges in his second corruption trial.

The Dauphin County jury also convicted Annamarie Perretta-Rosepink, Veon’s former manager of his district legislative office in Beaver Falls, on six counts of theft, conspiracy and conflict of interest charges.

Veon and Perretta-Rosepink were accused of misusing state grant money awarded to a nonprofit run by Veon.

Prosecutors said Veon used taxpayers’ money to pay rent on his legislative offices and provide a $4,000-a-month retainer to the Harrisburg law firm of his legislative chief of staff that required little or no work.

The 55-year-old Veon is already serving at least six years in prison on his 2010 conviction for using more than $1 million in taxpayers’ money for bonuses to reward legislative employees for campaign work.

In the trial, prosecutors said Veon used the nonprofit — the Beaver Initiative for Growth, or BIG — as a cover for the illegal diversion of taxpayers’ money for his own personal and political agenda. Defense lawyers said the state failed to prove its case.

Perretta-Rosepink, his former aide, has yet to serve a three- to six-month jail term for her conviction in the 2010 case.

Veon’s original sentence was the harshest imposed so far in a 5-year-old state corruption investigation into the misuse of taxpayers’ money for political purposes.
