Nicknames: No Known Nicknames
Location: Lake Andes, South Dakota
Date: December 12, 1992
Details: Arnold Archambeau, 20, and Ruby Bruguier, 19, were a teenage couple and the parents of an infant daughter in 1992. On December 12th, 1992 the couple and Ruby's cousin, Tracy Dion, 17, were involved in a horrible car accident in Lake Andes, South Dakota where they lived. The driver, Arnold, suddenly steered the car into a frozen ditch. The cousins, Tracy and Ruby, were inside the overturned car while Arnold was nowhere to be found. Ruby managed to escape, but didn't help Tracy out of the car for whatever reason. Luckily paramedics arrived a short time later and managed to pull Tracy out of the car and save her life. Tracy stated all three had been drinking the night of the car accident. Police Deputy Bill Youngstrom conducted a search for Ruby and Arnold as soon as he came could, but they were nowhere to be found the night of the accident.
In early March 1993 a passing driver saw a body in the frozen ditch where Arnold's car had crashed months earlier: Ruby Bruguier's decomposed body layed in the frozen ditch. Ruby's glasses and shoes were nowhere to be found, but her clothes remained intact. The police pumped the ditch out and at noon the next day they found Arnold's body submerged in the water, about 15 feet away from where Ruby was found. Arnold’s body wasn't as decomposed as Ruby's was: His skin color was fine, he wasn't frozen to the ground and neither were his clothes. Police didn't understand how both bodies were in two very different stages of decomposition when it was assumed they died at the same time. It was expected that Ruby and Arnold would've decomposed at the same rate. An autopsy later determined that both victims died of exposure.
A witness claimed to have seen Arnold and three other people on New Year’s Eve, almost three weeks after the car accident. The witness even took a polygraph exam and passed which indicated she hadn't lied about seeing Arnold on New Year's Eve. Ruby’s father, Quentin Bruguier, believed that his daughter and her boyfriend were victims of foul play and that the killer murdered them elsewhere and put the bodies back in the ditch to make it seem like they died there.
It is still unknown if the young lovers were victims of a homicide or an accident. A $5,000 reward is being offered in the case.
Suspects: None known, although authorities have been unable to locate two men who were seen near the ditch just a few hours before the bodies were discovered. They were driving a dark, blazer-style vehicle.
Extra Notes: This segment originally aired on the April 14, 1995 episode of Unsolved Mysteries.
Results: Unresolved. The FBI closed the case in 1999; they found no evidence of foul play and felt that the couple died accidentally. However, some officers involved in the case, along with the victims' families, still believe that foul play was involved.
