I was thinking that maybe Visions Ministries has some type of outreach programs for prostitutes or drug addicts and that is why these women travel so far to come there.
Also, I found this on the Suffolk County police blog. They are looking at Bittrolff as a possible suspect for another murdered woman 20 years ago.
Sandra Costilla, 28, of Queens was found dead in the woods off
Old Fish Cove Road in November 1993, and investigators believe her death could be linked to John Bittrolff, who was arrested on Monday and charged with the death of two other women, Suffolk County District Attorney spokesman Robert Clifford said.
