All Donna Hartley could think of as TV footage showed fires engulfing the town of Lahaina was her sister. But Carole Hartley wasn’t picking up her phone.

“I told my husband that if this is burned like this then Carole’s house is gone,” the 62-year-old said.

Two days later, her sister’s partner called, and the news wasn’t good. He told her that he had been in the front yard loading his car and Carole Hartley had been in the backyard, possibly checking on a tenant, when the wind fanned the flames. The car exploded.

After Carole’s partner assembled a team of friends for a search party, Donna Hartley heard the news Saturday night that he had found her sister’s remains, including her watch. She is still waiting for official DNA verification for her free-spirited little sister, who had lived in Lahaina for 36 years.

More than 100 people have been pronounced dead — making it the deadliest U.S. wildfire in more than 100 years.

“Her birthday was August 28, and she was going to be 61 years old,” Donna Hartley said. “She kept telling me as of late … one more year sister, and I’m retiring.” Donna Hartley said her friends at home in Grand Bay, Alabama, plan on holding a memorial for Carole.
