When she didn’t hear from him later that night, she called him but got no reply.

A few hours later, the mayor said, police called his daughter to tell her a man driving a stolen vehicle had run a red light and hit her husband’s Uber.

The stolen Jeep was traveling westbound on Colfax Avenue about 70 mph and hit the Uber headed south on Colorado Boulevard, Suthers said.

The Uber driver died immediately, he was told. Denver police spokesman Kurt Barnes would only confirm that one person was found dead. The Denver Post reported that the stolen Jeep also hit another vehicle.

“It’s a day-to-day situation,” Suthers said. “It’s a real tragedy. Janet and I love our son-in-law.”

Karla, a dentist, and Alison, a prosecutor in the Denver District Attorney’s Office, have been married about five years, Suthers said.

“He is just a very, very caring guy,” said Suthers, who went with him to Calcutta in November to help with his work.
