> Authorities allege Gehrke and King, who got married this year, knew charges were coming and had been preparing to flee. At their home, authorities found a book titled “How To Disappear: Erase Your Digital Footprint, Leave False Trails, and Vanish Without a Trace,” according to court papers. In one of their bags packed for their flight, there was a book titled “Criminal Law Handbook: Know Your Rights, Survive The System,”
I guess "step 15" from the book was "marry your criminal associates, so you're not forced to testify against each other": https://en.wikipedia.org/wiki/Spousal_privilege?
Step 1 should be "don't buy any incriminating books related to your planned disappearance" followed by the next chapter, "step 2: too late, already".
