Collins, a resident of Winter Haven FL, was mineral collecting in CO with 2 male friends. One returned to FL on a family emergency, then a few days later, the other returned driving Collins' pick-up truck. It was later discovered that that "friend" had taken out a $25,000 life insurance policy on Collins. The "friend" said that Collins had wanted to go to the Grand Canyon, so he dropped him off at a bus station in Colorado Springs. (Information retrieved from NamUs.gov)
