In August 2017, the Delta County Sheriff's Office opened an investigation into Richard Taylor, 49, for failing to register as a sex offender and being a convicted felon in possession of weapons. The case was filed with the Seventh Judicial District Attorney's Office.
In February 2018, another investigation was opened on Taylor for two additional counts of possession of firearms. This case was also filed with the DA's office. It was also believed at this time that Taylor was traveling and living between Delta County and the Denver area.

On April 13, the Delta County Sheriff's Office assisted ATF execute search and arrest warrants for Taylor and his residence of 43142 Needle Rock Road in Crawford. Taylor was taken into federal custody and additional firearms and ammunition were seized.
