After the body of 29-year-old Christina Nance was discovered in a van belonging to the Huntsville Police Department in Alabama last week, her family demanded answers.

On Friday, the department held a press conference showing a video in which Nance, who was not in police custody, reportedly entered the van by herself.

Nance’s family was shown the video on Friday morning before the press conference, according to a family representative. Police believe that she died after becoming trapped inside the van.

Authorities insist that her body showed no signs of foul play, but the family reportedly plans to conduct a private autopsy.

Police Hold Christina Nance Presser

At the Friday press conference, an HPD spokesman showed the video to an audience of reporters. The police spokesman said that the video was recorded around noon on Sept. 25 — almost two full weeks before Nance’s body was discovered on Oct. 7.

Police said the grainy footage was captured by a security camera attached to a police building, but “maintained” by the City of Huntsville General Services Department.

“It’s a city camera,” he told reporters.

The video displayed by police showed a figure on the far side of the parking lot, circling a squad car and shuffling through the lot before approaching the van where Nance’s body was discovered.

“Here’s where she goes along the side of the van,” the spokesman said, some seven minutes into the video. “You’ll see her go to the rear of the van, and then she doesn’t reemerge.”

He confirmed that he van was unlocked when police discovered Nance’s body last week, and said investigators believed the 29-year-old was trapped inside after she entered.

The van was purchased in 1995 to transfer inmates, police said. It was mostly repurposed in the early 2000s to transfer evidence, but would occasionally be used to transfer inmates who could not enter a squad car, such as those who are wheelchair bound.

Because the vehicle was designed to hold inmates, the spokesman said, there are no door handles on the inside. There is also a divider between the back compartment, where Nance was found, and the front seats.

“Once you get into the van you cannot exit from the interior of the van,” the spokesman said.

Footage from Sept. 28, officials said, showed that Nance had opened the van’s “pop-out” windows, a once-common feature on older vans.

“We just wish that she had hollered out to someone,” he continued. “There were plenty of what we see as potential opportunities for this to not be a tragedy.

But Christina Nance may have done just that — police noted that security footage for “several days” after Nance’s entry shows “movement” in the van, which may have been a cry for attention.

What’s more, Nance removed her shoes at some point and slipped them through the open window. The spokesman said that this small movement wasn’t picked up by the security camera.

“The more you zoom in, the more pixelated it becomes,” he said.

Nance might have intended for the shoes to draw attention the van, possibly hoping it would lead to her rescue. But help came too late.

By the time an officer noticed her shoes on the ground next to the van on Oct. 7, Christina Nance was dead. Officials said the cause of death is pending “full results” of an autopsy, but said a “preliminary” exam found “no trauma to the body, no signs of any foul play.”

Why Was the Van Unlocked?

Police could not explain Friday why the van where Christina Nance died was unlocked, allowing her entry.

The HPD spokesman said that all police vehicles should be locked, per department policy, when not in use. He noted that the van where Nance was found had not been used for any purpose since March, implying the vehicle was unlocked for six months when Nance entered.

“We’re looking at it as an accountability issue on our part,” he told reporters. “Sometimes you just have to say, this happened, and it shouldn’t have happened.”

HPD Said They “Knew” Christina Nance

The spokesman told reporters that the department had made contact with Christina Nance before through its Crisis Intervention Team (CIT), a division which “help[s] persons with serious mental disorders access medical treatment rather than placing them in the criminal justice system for illness-related behaviors,” according to the HPD website.

“Our department has worked with her,” he said Friday. “Our CITs know her pretty well, and we’ve worked with her in the past to provide resources. We are familiar with her.”

Asked to clarify, the spokesman declined.

“Well, our CIT unit works with those who struggle with any type of — I mean, the last thing we want to do is turn her into any kind of — she’s the victim here right?” he replied uneasily.

“But what I do want tell you is we do know her, we have worked with her,” adding that he did not know when the department last made contact with Nance.

Family of Christina Nance in Mourning

Huntsville police did not publicly identify Nance immediately after discovering her body. Instead, her family came forward after they were notified of her death, demanding more information.

“We really don’t know how our relative’s body was found inside a police van on police property and we need some justice,” said one family member last week.

On Friday, the family was shown the video ahead of the press conference. They did not issue a public comment except to confirm that they saw the video.

A GoFundMe page has been set up to assist the family with funeral and legal costs. Her sister described her as “a very good person,” “funny and fun,” and “loving.”

Nance’s loved ones are being represented by civil rights lawyer Ben Crump.
