A GRAD student has vanished after last being seen walking home from a bar in chilling surveillance video on Sunday.

Eliotte Heinz, 22, vanished on a 30-minute walk along the Mississippi River after leaving a night out with friends.

She was last captured on camera at approximately 3:20 am on Sunday while she was walking back home from Bronco’s Bar located in downtown La Crosse, Wisconsin, near the state’s border with Minnesota.

Eliotte was heading home to her apartment, which is about a 30-minute walk from the bar, her family said.

Police released the last-known picture of Eliotte, a grad student at Viterbo University, walking in a white T-shirt and jean shorts.

In the image, she appears to be holding her phone out in front of her.

Eliotte still hasn’t been found as of Wednesday.

Her family is desperate for answers, sharing the surveillance image of her and hanging up missing persons posters around the city.

“Sunday morning, we tried to reach her, and we were unable to get a hold of her,” Eliotte’s mom, Amber Heinz, told Fox News Digital. 

“We talk all the time. We talked to her that week.

“We were texting back and forth, but on Sunday morning when we couldn’t get a hold of her, we knew that something was going on.”

Her family asked anyone in the La Crosse area to check their home security camera footage from Sunday between 2 and 6 am.

“We ask that if you have seen anything — even if it’s small, anything at all, that you please call the La Crosse Police Department,” Amber said.

“If you have Ring cameras and you think that you might have captured an image of Eliotte, please call them, let them take a look at your footage.

“Even if you don’t think it’s a big deal, it might be something that’s a really big deal for her.”

Eliotte is studying mental health counseling at Viterbo University, her mom said.

Her family thanked volunteers for their support through search parties and donations in a statement on Tuesday.

“On behalf of our entire family, thank you,” the family said in the statement through Viterbo University.

“The community’s overwhelming support in the search for Eliotte has been deeply moving, and we are truly thankful for the kindness, prayers, and encouragement from both the local community and those further afield.”

The family continued, “Many of you have asked how you can help.

“At this time, the most important thing you can do is continue sharing Eliotte’s information on social media.”

Eliotte is described as 5-foot-4 and 120 pounds with blond hair and blue eyes.

LCPD didn’t immediately return The U.S. Sun’s request for an update on the ongoing search.
