According to Lynch, Pring-Wilson called 911 once Colono had left and when police arrived, professed to be a bystander to the incident.

Lynch argued today that Pring-Wilson “has attempted to avoid responsibility” and was “trying to cover up his wrongful conduct” by lying to the police.

But Denner said the misleading 911 call merely demonstrates his client’s traumatized state after the altercation.

“He could have balled up his yellow-slicker and thrown it away, but he called 911,” Denner said. “What he wants to do is have a hearing and regain his reputation.”

Colono later died at Beth Israel Deaconess Medical Center. Pring-Wilson was arrested at his apartment later that morning.

Before the district court bail hearing, Denner arranged for Pring-Wilson to undergo a polygraph test, in addition to medical evaluations.

Lynch argued yesterday that the court should not consider the results of the polygraph test—which supported Pring-Wilson’s claim that he would not leave town. She said polygraphs “are not scientifically accurate,” especially in predicting future occurrences.

Denner said Pring-Wilson would post bail this morning.

A pre-trial hearing is scheduled for May 30 at 11 a.m. in Middlesex County Superior Court.
