What we know from MSM since the bodies were discovered, but from BEFORE the ME confirmed that it was the girls:

Above, Heather states that the police are looking at specific people, but won't share the info with family.
Also, Jon Lieberman from HLN states that the police have "solid leads", are looking into the "meth connection" and "RSO's. he also states that his police sources regard 7 Bridges as the dump site, that LE has info they will not release to the public, and that the bodies were found 40-50 feet apart.
Abben seems to deny all of that.
Keep in mind that Drew firmly believes a sex offender is involved as he stated as much in the TV interview he did. I've got to believe that they have good reason to suspect a sex offender even though LE isn't saying it. Lieberman's word alone wouldn't convince me of anything, but with what Heather and Drew have stated publicly, I think Abben is downplaying the info they have.
