Two nearby but unrelated shooting incidents took place minutes apart police say, amid the crowded entertainment district of Austin, Texas, in the early hours of Saturday morning.

The first incident left one victim dead and four others injured. A separate incident ended with the gunman injured when bystanders helped detain the man after he fired his weapon during a fight.

Adam Summers used to trade Snickers bars to get free CT scans of dead fish.

He likes fish. A lot.

Summers is a professor at the University of Washington in the biology department and School of Aquatic and Fisheries Sciences.

"I've always been a fish guy," he says. "It's just been in my blood since I was as small as I can remember." Summers was a scientific consultant on Finding Nemo and did similar work with Finding Dory.

That father, Khizr Khan, condemned the Republican presidential nominee for proposing a ban on Muslims entering the United States.

A hot air balloon carrying at least 16 people crashed in central Texas after catching fire, and the Caldwell County Sheriff said "it does not appear there were any survivors."
