Seth Rich’s parents said their son wanted to change the world, and his death by gunfire in Northwest Washington on Sunday robbed him of that chance.

On Tuesday, Hillary Clinton, the presumptive Democratic presidential nominee, invoked Rich’s name to advocate for change of her own – pushing to limit the proliferation of guns. She listed mass killings and the shooting of Rich a block from his home in the Bloomingdale neighborhood.

“From Sandy Hook to Orlando to Dallas, and so many other places, these tragedies tear at our soul,” Clinton said in Portsmouth, N.H. “And so do the incidents that don’t even dominate the headlines. Just this past Sunday, a young man, Seth Rich, who worked for the Democratic National Committee to expand voting rights, was shot and killed in his neighborhood in Washington. He was just 27 years old.”

Clinton went on to implore, “Surely we can agree that weapons of war have no place on the streets of America.”

D.C. Police Chief Cathy L. Lanier, asked about Clinton’s comments about guns, said she would not comment on evidence, including what type of weapon was used in the shooting of Rich. Police said ballistic testing is still ongoing.

Rich had helped develop a computer program for the Democratic National Committee allowing people to type in their address and get a map to their polling place. He had moved to the District several years from his hometown, Omaha, Neb.

He lived in a shared townhouse on First Street Northwest, a block from where he was shot about 4:20 a.m. on Sunday at Flagler Place and W Street. Police said they are exploring attempted robbery as a motive; his parents said they believe their son was held up and was shot in the back when he refused to give up.

No arrests have been made.
