Tara Reid's allegations of drugging aren't necessarily false, but right now cops say their investigation's hit a dead end ... and they don't have any evidence to support the claims.

The Rosemont Police Department in Illinois tells TMZ ... no new evidence in the case has come to light, and the case is now closed.

We're told doctors didn't take chemical tests when Tara was rushed to a Chicago-area hospital last month ... so, they won't know exactly what -- if anything -- was in Reid's system at the time.

TMZ has obtained concerning video of influencer Mary Magdalene weeks before she died ... showing her being carted away by law enforcement officers in Thailand as she yelled out in confusion.

You can see in the clip, Mary -- whose real name was Denise Jarvis -- seems unable to walk on her own and is lifted by Thai officers and loaded into a cart on November 21 near the popular Krabi walking street. She exclaims she doesn't know what's happening as multiple men push the cart. The video then shows her being walked through a building and finally, into what appears to be a hotel room so she can rest in bed. She also appears to be claiming she's "drugged."

A second video shows her explaining she had been left on the street all by herself ... and says this is the price she pays for being "popular." She says she loves "the idea of being popular," but being left all alone and unable to help herself is not worth it, and "traumatizing." She even suggests people get pets for companionship instead and "isolate yourself from society."

An LAPD Robbery-Homicide detective showed up at the hotel where Nick Reiner was staying … looking for a weapon, blood, and other evidence connected to the murders of Rob and Michele Reiner … TMZ has learned.

A law enforcement source, along with two other people with direct knowledge, tell TMZ ... a Robbery-Homicide detective showed up at The Pierside Santa Monica hotel Monday around 1 AM, telling the front desk clerk he was there to do a welfare check on Nick Reiner, who was staying in room 207.

We’re told the detective said he was concerned Nick may have disposed of a weapon connected to a violent crime. The detective also said he believed Nick may have "cleaned up" and "disposed of evidence." We’re told hotel staff took the detective up to room 207, where he searched the room.

“Survivor” Season 48 contestant Eva Erickson narrowly dodged the gunman who opened fire at Brown University Saturday afternoon, but she says she's not overly worried about another shooting there.

Check out our interview -- the Ph.D. candidate says she feels "safe" while hunkered down at her off-campus residence in Providence, Rhode Island because she assumes the assailant is "long gone," reasoning ... "Lightning doesn't strike twice in the same place." On the other hand, she notes the idea is "horrible" because it feels like the shooter has gotten away.

As you know, there's an intense manhunt for the gunman by local and federal authorities, and the FBI is offering a $50,000 reward for information in the ongoing case. Providence Mayor Brett Smiley told ABC News Monday authorities "continue to receive zero credible threats to our community, Brown or the broader community," which he's certainly caught some flack for as the suspect remains on the lam.

While Eva feels safe overall, she tells TMZ she and her peers have just as much information as the general public, and the lack of knowledge about the assailant has everyone "on edge." She is pining for the answers to simple questions -- how and how such a tragedy could have happened.

One thing she's sure of -- something needs to change. Eva says it's "insane" students are so vulnerable to gun violence in America, noting ... "I just wanted to go to school and learn and have this community and be safe. And now that's been taken from me." While she says she doesn't have the answers, she looks at lawmakers who are better equipped to advocate for gun safety regulations.
