Looking at Terrant County's Daily Booked In Reports for yesterday -most recent one available-, there is a man who was arrested on the charge of "PV SEXUAL PERFORM CHILD" (PV = previous?).
Found him on Texas Department of Safety's Sex Offender Registry. He is currently 29 and was convicted of "SEXUAL PERFORMANCE OF A CHILD PRODUCE/DIRECT/PROMOTE" on 01/22/2015, so he would have been 27. Age of victim: 14.
It is a 30-minute drive from the apartment complex where Kaytlynn lives to his current address as listed on the RSO registry, so not terribly close.
According to vinelink, he is still in custody as of today.
