Picerno, who pleaded no contest in 2004 to bribery and conspiracy, is a former Oster political ally.

Oster faces two counts of bribery and two counts of conspiracy involving alleged bribes he and Picerno are said to have sought from potential buyers of the H&H Screw Co., about six acres on Route 116 in Lincoln. The state's case alleges Picerno and Oster conspired to extract a $25,000 bribe from Gelfuso in exchange for selling the property to Gelfuso and Daniel for $105,000.

Oster does not face charges with regards to the handling of the contract to renovate Fairlawn Playground, which is on different land, but Judge Gilbert V. Indeglia ruled the state could use it to try to demonstrate a behaviorial pattern by Picerno and Oster.

Under a prosecutor's direct examination, Gelfuso continued testifying this afternoon about his dealings with Picerno and Picerno's efforts to collect bribes from him. Gelfuso also talked about his working with the State Police.

Gelfuso said State Police were particularly interested in his getting Picerno to elaborate and specify what role, if any, Oster had in the scheme.

O'Brien questioned Gelfuso about events concerning his experience on the $150,000 playground renovation in the town's Fairlawn section.
