The statement also mentions the man accused of killing Cunninngham, Don Steven McDougal,42, after Texas DPS was able to connect him to Audrii's disappearance. 

The family said the system failed them due to a loophole in McDougal's criminal history. 

"Unfortunately, the system failed us due to a loophole in the sex offender registration system. Don Steven McDougal had a history of disrespect for young female children, but it did not show up when we checked the registry before allowing him to stay in an old camper in our backyard while he tried to start a new life. Had we been aware of what we know now, this man would never have set foot on our property, much less been a part of our little girl’s life," said Audrii's grandmother and father.
