A retired couple who met while serving in the Air Force together more than 30 years ago were fatally struck by gunfire, according to the Pittsburgh Tribune-Review.
Scott and Karen Marshall returned to Texas after completing an assignment at Maryland's Andrews Air Force Base, The Associated Press reports.

CBS Pittsburgh spoke with Scott's father who confirmed the news Monday on his 85th birthday.
"Heck of a birthday present," Robert said. "It's a shame that you can go pray and be shot up."
The family knew something was wrong when they saw news reports showing Scott's car parked in front of the church.
"We were praying that they were just going to be in the hospital, injured, not found dead in the church," Holly Hannum, the victim's sister, said.
Their worst fears were confirmed when Scott never answered their calls or texts.
"Scott and Karen were both wonderful people. Everybody that met them loved them, and they're going to be missed," Laurie Youngblood, the victim's sister, said.
"To lose them like that, it's heartbreaking," Fran Marshall, Scott's stepmother, said.
Robert says his son was a veteran who worked on jet engines and Karen was planning to retire from the military. His son was in Pittsburgh last week for an early birthday celebration before returning to Texas.
Now, Robert is trying to fly to Texas to be with his three adult grandchildren, but it may not be easy.
