As summarized on Wikipedia: The Bear Brook murders (also referred to as the Allenstown Four) are female American murder victims, two discovered in 1985 and two in 2000, at Bear Brook State Park in Allenstown, New Hampshire, United States. All four of the victims were either partially or completely skeletonized; they were believed to have died between 1977 and 1981. In 2017, investigators named Terry Peder Rasmussen as the most likely suspect. Rasmussen's identity was confirmed via DNA from a son from his first marriage. He was also confirmed, via DNA, to be the father of a 2-to-4-year-old girl who was one of the Bear Brook victims. Rasmussen is believed to be responsible for several other murders, including that of Denise Beaudin, his known girlfriend, who disappeared in 1981. Rasmussen was convicted and sentenced for the murder in 2002 of his then-wife; he died in prison in 2010. In 2019, the three biologically related females were identified as a mother, Marlyse Elizabeth Honeychurch, and her two daughters (of different biological fathers) Marie Elizabeth Vaughn and Sarah Lynn McWaters, last seen in November 1978. The middle child, identified as Rasmussen's daughter, currently remains unidentified. Based on the date they disappeared, available documents and Rasmussen's activities, the victims most likely died between 1978 and 1981.
