Transit Police report they are looking for a guy they say started an argument with another passenger, then " struck him on the side of the head with an unknown object" around 2 p.m. on Sunday.

If he looks familiar, contact detectives, anonymously if you like, at 617-222-1050.

Update, 9:15 p.m.: WFXT reports suspect is dead.

WCVB reports that authorities are looking at a possible connection between Saturday's mass shooting at Brown University that left two dead and Monday's murder of MIT nuclear physicist Nuno Loureiro at his Brookline home.

WBUR reports that the latest effort over more than a century to consider extending the Orange Line south of Forest Hills got a boost in the state House, which passed a proposal by state Rep. Bill McGregor (D-West Roxbury) and state Sen. Mike Rush (ditto) to throw some money MassDOT's way to look at what would be involved in getting the line extended to Roslindale.

Forest Hills has been the southern terminus of what is now the Orange Line since 1909, but not for lack of trying.

In 1916, the state Public Service Commission considered a proposal by one of its engineers to extend what was then the Boston Elevated's Main Line from Forest Hills to West Roxbury by adding a third rail along what is now the Needham Line. 

Nothing, of course, ever came of that, even though the commission concluded that "the cost would be trivial as compared to rapid transit lines on elevated structures or in subways" and would serve a fast growing area (bonus fun facts: At the same time, the commission also recommended changes in signaling to permit trains every 90 seconds on the line - and to electrify what is now the Fairmount Line).

In 1947, the Metropolitan Transit Recess Commission proposed extending the line all the way to Dedham, along with extending the Red, Green and Blue Lines (and the northern end of the Main Line):

The plans for this route proposed an extension of the present Everett-Forest Hills line by way of the tracks of the New Haven Railroad, West Roxbury Branch, to Dedham. All of the proposed stations on the line would require high level platforms to permit the same kind of operation as now exists in the Washington Street Tunnel. From the present elevated station at Forest Hills, the new route would pass by way of an underpass under the tracks of the New Haven Railroad (Boston & Providence) and thence by an incline to the present grade of the tracks of the West Roxbury Branch.

The proposed stations on this line would be at approximately the same locations as the present railroad stations and would be Roslindale, Bellevue, Highlands, West Roxbury and Dedham. This extension would provide the people of the West Roxbury area with a more frequent service which would avoid a transfer at Forest Hills and would also avoid the obstacles incidental to surface car operation.

The West Roxbury Branch split off from the rail line near the present location of the West Roxbury Star Market on Spring Street on its way to the Dedham train station - by way of a bridge across Spring Street, the last abutment for which was only taken down last year. The site of the Dedham station is now a town parking lot.

Around the same time, though, another state commission chaired by the guy who built the Massachusetts Turnpike was recommending turning Boston into a series of eight-lane expressways and the like so that suburbanites could speed right downtown. You can guess which idea won - at least until 1970, when Gov. Sargent canceled all the unfinished highway projects inside 128.

In 1966, when highway mania still ruled, the MBTA itself considered expanding the Orange Line - with three new branches from Forest Hills - starting with an extension down the Needham Line tracks to a station at VFW Parkway, where the T proposed building "a large parking area," roughly where West Roxbury High School now crumbles.

Once that was built, the T wanted to look at continuing that extension into Needham and then building two more branches. One would head down the Southwest Expressway median from Forest Hills through Jamaica Plain, Roslindale and Hyde Park to the 128 train station. The other would branch off from that extension at Readville and run along the Franklin Line through Norwood and Westwood. Those two branches would have required the New Haven Railroad to move its commuter-rail service, which then ran through Readville, to what is now the Fairmount Line.

As with the earlier proposals, these soon disappeared as well.

The Boston Licensing Board today granted valuable full liquor licenses to restaurants in three neighborhoods.

The licenses are different from the neighborhood licenses the board has been granting over the past year because unlike those, which have to be returned to the board should the recipients close or move, these become as close as licenses get to property - they can be used as collateral for loans or even sold, at prices that currently approach $600,000. The board has nine more of these licenses to dole out, which members said they would do over the next year.

Board members said today that Gracenote Coffee, 108 Lincoln St. in the Leather District, Meringue Express, 1415 Tremont St. on Mission Hill, across from the Roxbury Crossing T stop, and Ama, 100 Western Ave. in Allston, all demonstrated the unique proposals, roles in making their neighborhoods more vibrant and responsibility that the board was looking for.

Gracenote Coffee, which offers "curated listening room programming," would increase the cultural vibrancy of the Leather District for both downtown workers and visitors, board members said, adding there's a relative lack of liquor licenses in that neighborhood.

More Gracenote details, discussion at hearing:

Meringue Express, which offers Dominican food, has been actively involved in the community and said it would use its new license to accentuate its food offerings, not to become a bar or late-night hangout.

More Merengue Express details, discussion at hearing:

Ama, in the new Atlas Hotel in Harvard's Allston development off Western Avenue, is by the same team behind Dorchester's award-winning Comfort Kitchen, promising to carry that restaurant's "proven community-oriented concept into a growing area," board Chairwoman Kathleen Joyce said.

More Ama details, discussion at hearing:

The board set a deadline of Jan. 16 for new applications for the remaining nine unrestricted liquor licenses it has. Board members said that any applicants before the board's previous deadline of this past May 23 would also be considered.
