I'm still reviewing the facts here, but from what I've seen so far, the person in question, JF, has been named in MSM. He has a criminal record as a sex offender, and had contact with Jaimee the night she disappeared. His van was seized by LE, as well. Therefore, he can be discussed. This is different from a case where a RSO's lives in the area, but is not known to have had contact with a missing person or victim. Although this person has not been officially named a POI or suspect, according to MSM he is being investigated as such.
