When James and Michelle Butler left New Hampshire in June in a pickup truck and a secondhand RV - James had traveled the world with the Navy, he told people, and now he wanted to see the United States - the couple stayed in near-constant contact with friends and family.
Out west, they told relatives when they'd be off the grid and reached out as soon as their service returned, remembers James' sister, Deborah van Loon. Loved ones looked forward to regular FaceTime calls and Facebook photos, reports The Washington Post.
In mid-October, the communication stopped.
On Oct. 27, a woman's body was found buried in a shallow grave on the Texas beach where the Butlers were last seen camping, officials with the Kleberg County Sheriff's Office told media. A day later, authorities discovered a man's body underneath. And on Friday evening, van Loon got a call from law enforcement: The bodies belonged to her brother and his wife.
The deaths, ruled homicides by a medical examiner, are still under investigation, the Associated Press reported. Authorities have video of the Butlers' truck and trailer crossing into Mexico, driven by someone else, according to CBS Boston.
