The crash site is about 20 miles from where Ethan Manzano and Sophie Rayanne Edwards, both 19, were last seen on July 1.
Sheriff's officials said the vehicle was spotted at about 5:20 p.m. Tuesday near mile marker 72 of the Angeles Crest Highway, near Dawson Saddle Trail. Chad Keel, a Wrightwood resident who was helping search for the missing couple, told reporters he was operating the drone that spotted the wreckage and volunteers contacted the sheriff's department.
Authorities are still in the process of determining the vehicle's owner.
2 bodies found amid search for missing couple last seen in Angeles National Forest
The couple were in a silver 2007 Isuzu Ascender with California plates 6BFA756 driven by Manzano, sheriff's Deputy Shawn Du Busky said.
Some of the couple's belongings were also spotted near the crashed vehicle, which was found about 1,300 to 1,500 feet below the roadway, partially obscured by brush. Two bodies are inside the vehicle, but they have not been positively identified.
Friends and relatives, however, fear the worst.
"I can't believe I'm going to be burying my son. He was only 19,'' Manzano's father, Al, said.
"She was an amazing young lady, very intelligent and kind and just full of life and spunk," said Cheyenne Chassie, Edwards' sister.
Ethan Manzano and Edwards, his girlfriend, were visiting friends in the Newcombs Ranch area but left around 1:30 a.m. on July 1 to drive home to Apple Valley. They never arrived. The couple were planning to move to Colorado over the Fourth of July weekend.
Investigators speculate that the vehicle's driver veered off the winding roadway, sending the vehicle careening down the hillside.
The California Highway Patrol was overseeing the recovery effort, with help from the Los Angeles County fire and sheriff's department.
Anyone with information of the couple's whereabouts is asked to call the LASD's Missing Persons unit at 323-890-5500 or 911. Tipsters can also call Crime Stoppers at 800-222-8477.
