A woman who possibly had a medical issue died Sunday afternoon in a single-vehicle wreck in Arlington, police say.
She was later identified by the Tarrant County medical examiner's office as Diana Jemes, 61, of Wylie.
Jemes veered off Interstate 20 in the 5500 block and down an embankment, crashing at Green Oaks Boulevard shortly after 3:30 p.m., police say.
Police said Jemes called her daughter shortly before the crash. She told her daughter she thought she was having a heart attack and was going to try to drive herself to a hospital.
"Very sad case," said police spokesman Christopher Cook.
