The latest school involved in a deadly mass shooting previously helped Virginia Tech heal after its own deadly campus rampage more than a decade ago.

Virginia Tech President Timothy Sands tweeted a link Friday to the school's condolence archive, which catalogs the items it received after a gunman fatally shot 32 people in 2007. Among them is a handmade book from Marjory Stoneman Douglas High School in Parkland, Florida.

"We will never forget that you helped us to heal," Sands said.

The shooting at Virginia Tech was, at the time, the deadliest mass shooting in recent U.S. history.

Authorities said a 19-year-old who'd been expelled from the Florida school opened fire there Wednesday, killing 17 people and wounding more than a dozen others.
