The former chief of staff to Councilman Jack Kelly, his ex-campaign treasurer, and one of Kelly's chief campaign contributors were convicted by a federal jury yesterday of a conspiracy to buy influence in City Hall.

But the jurors rejected most of the bribery, mail-fraud, and wire-fraud charges against former Council aide Christopher Wright, ex-campaign treasurer Andrew Teitelman, and developer Ravinder "Ravi" Chawla. A fourth defendant, Hardeep Chawla, Ravi's brother, was acquitted.

Wright, 45, was found guilty on three of 13 counts that accused him of selling his services as Kelly's top aide to the Chawlas and Teitelman, the developer-brothers' company attorney.

Ravi Chawla was convicted on four of 12 counts, Teitelman on three of nine counts. Jurors came back with a verdict at 11 a.m., in their sixth day of deliberations. The trial began Jan. 27.

The three remained free on bail and face sentencing in May, with each facing approximately four to six years in prison, though the sentences could vary on either end.
