NEW BRITAIN, Conn. -- A Wethersfield woman arrested at her home by a Connecticut state trooper last week left court in New Britain Monday after the charges against her were dismissed.

“I’m very relieved that the charges were dismissed,” Sharon Gentino said.

The Channel 3 I-Team reported last week that Gentino was arrested Dec. 4 when she was approached at her home by Lanati.

The I-Team was told Lanati took it upon himself to investigate what he said was a school-yard fight between Gentino’s son and another child at Webb Elementary School. Sources said Lanati, a 9-year veteran who was on-duty at the time, launched the investigation on his own after getting a cell phone call from his neighbor, who is also the other child's parent.

Gentino called Wethersfield police when Lanati arrived, but before they got to the scene, Lanati had placed her under arrest on charges of interfering with his investigation and breach of peace.

Gentino's court appearance Monday was short as prosecutors dropped all charges against her.

After reading police reports and investigating what happened, New Britain State's Attorney Scott Murphy said, “Using my discretion, I believe prosecution is not appropriate in this matter."

“They did a great job in investigating this as quickly as possible and in refusing to prosecute this today,” Defense Attorney John Swanson said.

Meanwhile, Connecticut State Police are conducting an internal affairs investigation into Lanati's decision to investigate the assault of an acquaintance's child and his decision to arrest Gentino.

A state police spokesman said the dismissal of the charges does not necessarily impact that investigation.

Numerous representatives of local police departments contacted by the I-Team said it’s highly unusual for a state trooper to investigate this type of crime in a local police department's jurisdiction.

Gentino's lawyer said she'll speak to internal affairs investigators later this week and has not ruled out taking further legal action against the trooper.

“We're just going to get through today, be glad that we don't have to appear here in criminal court again, and we'll regroup and consider what our next course of action is,” Swanson said.

State police said they aren’t putting a timetable on the internal affairs investigation into Lanati's actions.
