PROVIDENCE — Benjamin W. Geldmaker, the 18-year-old Barrington man who bought alcohol that may have played a role in a fatal car crash in Barrington last month, was fined $500 in District Court yesterday, and ordered to undergo substance-abuse treatment.

Judge Michael A. Higgins also ordered Geldmaker, of 128 Maple Ave., to return to court Jan. 31 to make sure he is complying with the mandatory counseling.

It’s the second time since he turned 18 in January that Geldmaker has been arrested for misdemeanor underage alcohol possession, according to Barrington police Lt. Lee A. Soito.

He was cited June 18 and ordered to pay $150 plus court costs.

Yesterday, because it was a second offense, Soito said, the fine was $500.

Geldmaker stood accused of going to Douglas Liquor in East Providence on Nov. 5 and using fake identification to buy a 30-pack of beer. He gave about six cans to a 17-year-old acquaintance, also from Barrington, who took it to an informal party involving several local youths.

Four of those teenagers got into a car later that evening and the driver, whose identity has been kept secret because he was 16, slammed into a tree, killing passenger Jonathan Converse, also 16.

The driver, who was allegedly traveling at more than twice the 25-mph speed limit and operating under a provisional license, which prohibited him from having more than one friend in the car, has been charged in Family Court with driving to endanger, death resulting, and refusing to submit to a breath test.

The attorney general’s office has asked that the driver be tried as an adult. A hearing on that motion has been scheduled for Monday.

The 17-year-old for whom Geldmaker got the beer — who was, like Geldmaker, charged with underage possession of alcohol — was told he could either spend at least five days in the state Training School or 90 days in Family Court’s juvenile drug and alcohol court. He picked the court.

Two other Barrington youths, ages 16 and 17, chose the same penalty after being accused of buying the bulk of the liquor for the party — three 30-packs of beer from S&M Liquors in Providence.

In addition, the former hockey players were banned from all athletics by Family Court Chief Judge Jeremiah S. Jeremiah Jr., who called one of them “a disgrace to the community.”
