The gunman who killed two students at Brown University was found dead in a storage unit after murdering an MIT professor as their decades-old connection was revealed.

The suspect - 48-year-old Claudio Neves Valente - was revealed to be a Portuguese national who studied at the Ivy League school in Rhode Island more than 20 years ago.

He had attended Brown to pursue a masters of science in physics from 2000 to 2001, before he took a leave of absence and ultimately withdrew from the school.

It remains unclear why Neves Valente opened fire at the Rhode Island school, killing Mukhammad Aziz Umurzokov, 18, of Virginia, and Ella Cook, of Alabama, 19.

But University President Christina Paxson said it was likely he took classes inside that building when he attended the school.

Neves Valente opened fire during a study session at the Ivy League's School of Engineering Barus and Holley Building on December 13.

Two days later, he fatally shot MIT Professor Nuno Loureiro inside his Boston home.

Authorities revealed that gunman original target was Loureiro and the pair had attended the same school in Portugal from 1995 to 2000.

It was unclear what the shooter's motive was or what his relationship with Loureiro had been.

The suspect was ultimately found dead after a six-day manhunt, when authorities located a vehicle he used parked outside of a storage facility in Salem, New Hampshire - more than 80 miles from the Ivy League school.

Do you actually in your heart of hearts have the audacity to think that your Government}To Wit The Government of The United States of America would tell you a falsehood?

the killer of two murders with suspiciously small amounts of evidence was found dead in a storage unit.

blaming everything on the dead guy is just lazy writing.

How did this guy have the escape plan to get all of these people, then shoot himself in a storage shed?

I am not believing this.

Very strange why he would seemingly target two kids who weren’t even born when he attended Brown.
