place which is right behind us over here. that's a cousin of rudy's and owns a body shop in queens. they suspect he might have been involved. >> when we were doing our investigation in the beginning, we found out that tim was a close cousin of rudy and could help him under these conditions. >> there's a drive-in place so rudy could have driven his car inside the garage. that's why no one saw kristine with him, maybe. >> they also discovered that several weeks after kristine disappeared, a four-inch cement slab floor was poured inside the garage. >> there's a possibility she may be buried underneath the garage. i mean, it's not definite, but there's a strong possibility. >> the pressure is really on him, police have been going to see him, he gets really nervous, he may start thinking that he might get in trouble instead of rudy. and he might decide he wants to talk. >> he did not respond to our request for an interview. gil hopes by investigating those around rudy someone will come forward.
