The Los Angeles County coroner's office is investigating the death of Peggy Frank, 63, who was found unresponsive in Woodland Hills as temperatures shot to at least 115 degrees, according to the Los Angeles Times.
A doctor has ordered tests to determine whether Frank's death was related to the heat, the newspaper reported. The tests are expected to take between four and six weeks, according to the Los Angeles Daily News.
Paramedics attempted to revive Frank after she was found Friday afternoon, but she was pronounced dead at the scene, according to KCBS-TV. She had worked for the Postal Service for more than two decades and was just a few years from retirement at the time of her death, according to the newspaper.
