Here’s the latest.

The authorities on Thursday identified a person of interest in the shooting at Brown University last weekend and are investigating whether there was a connection to the killing earlier this week of a Massachusetts Institute of Technology professor, according to two people briefed on the matter who were not authorized to speak about the investigation.

Investigators are searching for the individual and a car that the person is believed to have rented, one official said. The authorities have not publicly identified a suspect in either case. Investigators believe the rented vehicle is the same make and model of a car identified in connection with the shooting Monday night of the M.I.T. professor in Brookline, Mass., the official said.

Last Saturday, a masked gunman dressed in black burst into a lecture hall in the Barus and Holley science building at Brown and fired at students who had gathered for a review session before final exams. Two students were killed, and nine others were injured.

On Monday night, the authorities in Brookline were called to the home of the M.I.T. professor, Nuno F.G. Loureiro, who had been shot. He was pronounced dead on Tuesday morning. Ted Docks, the special agent in charge of the F.B.I. in Boston, initially said there seemed to be “no connection” between the attack at Brown and Dr. Loureiro’s death.
