Campus police at the University of Massachusetts Amherst are looking to identify a handful of people allegedly involved in the disturbance after the New England Patriots’ Super Bowl loss on Feb. 5, in addition to those already arrested. Rowdy demonstrations after the game ended with the arrests of 13 students and one non-student. The students will face school sanctions as well as criminal charges, officials said. Six pictures posted on the campus police website show a group of people milling about outside, including one woman wearing a bathrobe, but no shoes. One picture shows a young man wearing a Patriots jersey after coming through a door. Authorities are asking that anyone who knows the individuals’ identities call police.

Burlington and State Police converged on the Burlington Mall area this afternoon after someone reported a man possibly armed with a shotgun. But it turned out there was no “active shooter” and the weapon involved was a BB gun, State Police said. Burlington police have identified a “person of interest” and are investigating, State Police said. Last April, the mall was evacuated and heavily armed police scoured the buildings following reports that an armed man was making his way through the shopping center. Police later learned the object was an umbrella.

At least 11 more dolphins have stranded themselves on the shores of Cape Cod this morning as the mass strandings enter the second month. The International Fund for Animal Welfare said at least one of the 11 had died. The animal welfare group said the dolphins were found in an area commonly known as “the gut,” a muddy area near the Herring River in Wellfleet. “The team is out there now with 10 live dolphins,” spokesman Michael Booth said. “It could take quite awhile; it’s a treacherous location with lots of mud. The team is trying to pull them out of the mud and bring them to our rescue trailers.”

More than 400 public transit riders blasted the Massachusetts Bay Transportation Authority’s proposed rate hikes and service cuts last night in Boston, insisting that the measures would harm the poor, the elderly and disabled, and students. “How much do you expect the poor to pay?” said Jane D’Angelo, 47, during a public hearing hosted by the MBTA on the proposed changes at the Boston Public Library’s main branch in Copley Square.

Boston officials found cause for both optimism and concern as they combed through President Obama’s proposed $3.8 trillion federal budget. City officials said they were encouraged by the commitment shown to paying for schools and roads. They also praised an estimated 20 percent increase in grants to combat homelessness. They expressed concern about a proposed cut to heating assistance for low-income families and the effect a reduction to a public health program would have on obesity prevention and smoking cessation.

The Massachusetts Water Resources Authority is proposing to raise the wholesale price of water and sewer service to communities it serves by 3.9 percent. In a proposed budget, the agency said the increase would equate to about $17 for households that use the average 61,000 gallons per year. The agency said the rate increase is part of a three-year strategy that began in fiscal year 2011 with a 1.49 percent increase and called for 3.9 percent increases in fiscal years 2012 and 2013. “Back when we developed the FY11 budget, we wanted to try and minimize increases because of the uncertainty of the financial picture,” MWRA spokeswoman Ria Convery said. “That [FY11] was our lowest rate increase in 15 years. We wanted to make the following years something predictable and affordable.”

Francis McDonald is not an actor. He knows the seven seas better than the silver screen. Still, he was hoping today that he might get a role in an upcoming Tom Hanks film. “It would be an honor to be cast in the film,” he said. “The chance, like anything in this business, is a long shot. It was very enjoyable nonetheless.” McDonald, vice president for operations at the Massachusetts Maritime Academy in Bourne, was one of more than 40 people to audition for four parts in Columbia Pictures’ planned film about the 2009 hijacking of the cargo ship Maersk Alabama, starring Tom Hanks as captured Captain Richard Phillips. Phillips was a 1979 graduate of the Maritime Academy.

Some 275 Harvard University employees will be offered voluntary buyouts in the school’s first concrete move toward modernizing its decentralized library system, university officials said today. Workers there have worried about layoffs, which they were told to expect during a contentious set of internal meetings in January that led to protests – most recently, the “occupation” of a library café on Sunday by students and activists. But the packages offered today are “totally voluntary,” said a letter from Marilyn Hausammann, Harvard’s vice president for human resources.

A federal magistrate judge has set Nov. 5 as the date for the trial of 82-year-old gangster James “Whitey” Bulger, rejecting claims by Bulger’s lawyers that they needed another year to prepare for the trial. US Magistrate Judge Marianne B. Bowler set the date in a hearing today in US District Court in Boston. She said she wanted to keep a close eye on the progress both sides were making in getting ready for trial and set a status hearing for March 19. Federal prosecutor Brian Kelly argued that Bulger was trying to avoid a trial. “Frankly, it appears to us that Mr. Bulger is trying to run out the clock and delay it so he doesn’t have a trial,” he said.

The state’s highest court has ruled that people can be charged with possession with intent to distribute marijuana even if they were caught with less than an ounce of the substance, despite the decriminalization of simple possession of such small amounts. The Supreme Judicial Court said a 2008 referendum that changed possessing less than an ounce from a criminal offense to a civil offense had no effect on the separate law that makes it a crime to possess marijuana with the intent to distribute it. “We conclude that the passage of [the referendum] did not repeal the offense of possession of marijuana with intent to distribute [...] where the amount of marijuana possessed is one ounce or less,” Chief Justice Roderick Ireland wrote in today’s opinion.
