Police investigate links between Brown shooting and killing of MIT professor

Sources say person of interest identified in attack at university and death of prominent physicist 50 miles away

Authorities said Thursday that they're looking into a connection between last weekend's mass shooting at Brown University and one two days later near Boston that killed a professor at another elite school, the Massachusetts Institute of Technology.

That is according to three people familiar with the matter who were not authorized to discuss an investigation and spoke on condition of anonymity. Two of the people said investigators had identified a person of interest in the shootings and were actively seeking that individual.
