The medical examiner’s office said in a news release Wednesday that it found the jewelry and some of the cremated remains of the couple, a man named Christopher “C.J.”
Stapleton and a woman named Kristina Stapley, in their car along Interstate 95 in Palm Beach Gardens on Dec. 24, 2018.
The medical examiner also said they left behind a note on their vehicle, according to the release.
The notes were found at a funeral home, according the release, which did not identify the funeral home.

The couple’s family and neighbors said the couple died in a fire.
The Staples were cremed at a casket in Palm Springs, California.
