John Bickley

He was enrolled in a Ph.D.

physics program from the fall of 2000 to the spring of 2001.

It's not clear yet what brought him back to Brown, but what authorities are certain of is that they found their guy.

They found his body in a storage locker he had rented, dead by suicide.

Police released images of him renting the car that they tracked him with.

And in those images, he's wearing the same coat as the person of interest in the photos released earlier this week.

Same build, also the same fanny pack.

Neves Valenti also had two firearms on him when they found him.

Now, authorities reported earlier yesterday that they had found DNA evidence of the gunman at the crime scene.

Presumably that will match with Neves Valenti to further seal this case.

Officials said last night that this case really broke wide open after they released images of a second person of interest on Wednesday.

Within a couple hours, that person had come forward, given police crucial information about the vehicle, and through the vehicle, police were able to identify Neves Valenti and eventually track him to that storage locker in New Hampshire.

Law enforcement converged on it.

Dozens of local, state, and federal agents surrounded the place before they finally opened it up and found Neves Valenti dead inside.

Now, this breakthrough came at a pretty tense time between officials and the local community.

If you watched any of these press conferences this week, you could see the frustration between reporters and the officials.

Officials have taken a lot of heat for the pace of the investigation and for the competency of those in charge.

For instance, here's a viral clip of the Providence chief of police, Oscar Perez, struggling to answer a question on the basic facts of the case.

Right, and New Hampshire authorities confirmed that suspected connection last night as well.

They said that Neves Valente murdered MIT professor Nuno Lauriero in his Brookline home.
