The footage shows Christine Englehardt, of Richboro, walking into her South Beach hotel with Evoire Collier, 21, and Dorian Taylor, 24, at 12:59 a.m. on March 18, then leaving at 1:36 a.m., Local10 reports.
Englehardt was found drugged robbed and raped -- and neither Collier nor Taylor have been charged in her death.
The newly-released footage could be a key piece of evidence in the case.
A GoFundMe in Englehardt's memory had raised more than $61,000 as of May 19.
