So, this reminds me of another serial killer that I heard from the My Favorite Murder podcasters. In an interview, they talked about a serial killer from Alaska (sorry I forgot his name but I will look it when I have the chance too) that worked as a contracted and traveled around the country. His MO was described that he would create these "kill kits" where he would hide them in the woods, near the spot where he would wait for his victims and then once he kidnaps them he would take out the kill kits and get the job done. He then would hide the body and the destroy the kill kits so he won't be caught having them in his possession if the police did stop him. Once the FBI found him he basically committed suicide so he won't go to prison.
Edit:
I just found the name of that serial killer they were talking about. His name was Israel Keyes:
On March 16, 2012, Israel Keyes was arrested in Lufkin, Texas after he used a debit card that belonged to an 18-year-old Alaska woman that he killed and dismembered in February. During the following months, while awaiting trial for the murder of Samantha Koenig, Keyes confessed to seven other murders during more than 40 hours of interviews with the FBI.
Investigators believe there are at least three more victims and possibly much more.
It goes on:
SETS UP BASE IN ALASKA
By 2007, Keyes established Keyes Construction in Alaska and began working as a construction contractor. It was from his base in Alaska that Keyes ventured out into almost every region of the United States to plan and commit his murders. He traveled many times since 2004, looking for victims and setting up buried caches of money, weapons, and tools needed to kill and dispose of the bodies.
His trips, he told the FBI, were not financed with money from his construction business, but from money he got from robbing banks. Investigators are trying to determine how many bank robberies that he may have been responsible for during his many trips across the country.
It is also unknown at what point Keyes escalated to committing random murders. Investigators suspect it began 11 years before his arrest, shortly after he left the military.
MODUS OPERANDI
According to Keyes, his usual routine would be to fly to some area of the country, rent a vehicle and then drive sometimes hundreds of miles to find victims. He would set up and bury murder kits somewhere in the targeted area - stashing items like shovels, plastic bags, money, weapons, ammunition and bottles of Drano, to help dispose of the bodies.
His murders kits have been found in Alaska and New York, but he admitted to having others in Washington, Wyoming, Texas and possibly Arizona.
He would look for victims in remote areas like parks, campgrounds, walking trials, or boating areas. If he was targeting a home he looked for a house with an attached garage, no car in the driveway, no children or dogs, he told investigators.
Finally, after committing the murder, he would leave the geographic area immediately.
