A jury has been seated, and opening statements were delivered Monday in the federal trial of a Masury man accused of participating in a scheme to defraud a regional healthcare nonprofit of more than $2 million.

U.S. District Judge J. Nicholas Ranjan in Pittsburgh is hearing the case of John O’Brien, the last of five defendants to face trial in the case involving the Primary Health Network, a Sharon-based organization that provides medical services to underserved communities. While four other men charged in the investigation have pleaded guilty, O'Brien has maintained his innocence.

Lawyers for the government and the defense questioned potential jurors on Monday. Both sides used strikes to remove certain individuals from the pool until the final group was seated.

Attorneys for the government and defense delivered their opening statements to the jury. The statements provide an overview of the evidence each side plans to present during the trial.

O’Brien faces charges of conspiracy to commit mail and wire fraud and three counts of wire fraud. Prosecutors allege that between 2011 and 2019, officials at the health network steered funds to themselves through deceptive business practices. O’Brien specifically controlled a company called Tele-Data, which investigators claim was used to take money from the nonprofit.

The trial is expected to continue on Tuesday morning. If convicted, O’Brien could face a prison sentence of up to 20 years on the most serious fraud counts.
