It was the last time her co-workers saw the 50-year-old Tonganoxie woman alive.
Knapp died in a two-vehicle collision shortly after 1 p.m. Sunday in Jefferson County. The Kansas Highway Patrol said the 1998 Ford pickup truck she was driving crossed the center line on Ferguson Road about 6 1/2 miles north of U.S. Highway 24.
Also killed in the accident was the driver of the other vehicle, Randy Russell, 38, Lawrence.
The Highway Patrol report gave no details why Knapp's truck crossed the line. The trooper who investigated the accident couldn't be reached for comment. Family members also couldn't be reached.
Employees at Presbyterian Manor wonder if Knapp had a heart attack.
"She hadn't been feeling well lately," said Judy Saragusa, who worked with Knapp in the laundry room. "She didn't like to go to doctors. She always thought what she didn't know wouldn't hurt her."
Knapp wasn't the type of person who would let her attention lapse, said Judy Fabert, director of human resources at Presbyterian Manor.
Manor employees are saddened by Knapp's death, Fabert said.
"She was really well liked and very well thought of by everybody," Fabert said.
Knapp and her husband, Brad Earl Knapp, had a residence at Lakeside Village near Lake Perry in addition to their Tonganoxie home, said Saragusa, who also lives at Lakeside.
"I've lost a close friend," Saragusa said.
Capital Cities Mortuary Services, Topeka, said cremation was planned with a private memorial service for the family at a later date.
