A Jacksonville State University student remains in critical condition two days after she was hit by a vehicle in a crosswalk near campus.

Leah Tarvin, 22, was struck at 5:54 p.m. Wednesday in a crosswalk on Highway 21 near Brewer Hall. She was treated on scene by Jacksonville Fire and EMS medics and then airlifted to UAB Hospital in Birmingham.

Jacksonville Police Chief Marcus Wood on Friday said Tarvin’s condition remain “very” critical.

“Jacksonville Mayor Johnny Smith and our City Council members want to express their deepest concern and heartfelt prayers to Leah and her family,’’ according to a Facebook post by the City of Jacksonville on Facebook. “This incident and others like it are tragic and heartbreaking. We ask everyone to please pray for Leah and her family, and to show them the spirit and love that lives in every part of our community.”

The Jacksonville Police Department is leading the investigation, with assistance from the Alabama Law Enforcement Agency and JSU police.

Tarvin, 22, is from Cullman County. She graduated from Holly Pond High School and then attended Wallace State. She is currently studying forensic investigations at JSU.

On Thursday, JSU officials said accidents like Tarvin’s have “unfortunately, become all too common at JSU.”

“For decades, members of the JSU community have been injured or even killed while crossing the two state highways that intersect our campus,’’ according to a JSU statement. “We have already had four pedestrians injured in three accidents on these roadways this year.”

“Since Highways 21 and 204 are state-controlled, it limits the university and city’s ability to make improvements to keep our community safe,’’ the statement read.

“Representatives from the university and the City of Jacksonville have met with the Alabama Department of Transportation as recently as March to request their assistance but were told the crash data does not warrant any additional precautions. We have already reached out, once again, for assistance.”

JSU officials urged others to voice their concerns to the ALDOT.

“This is a heartbreaking situation, and the university will continue to fight to protect our community,’’ officials said.

ALDOT spokesman Tony Harris said officials have talked with JSU officials about their concerns.

“The pedestrian crosswalks on state highways around the JSU campus received upgrades of a few years ago as part of a cooperative project between JSU and ALDOT,’’ Harris said. “The crosswalks are marked with advanced warning signs and other devices to warn drivers to yield for pedestrians, which is required by state law.”

“We will work with university officials to see what else can be done,’’ Harris said.

Chief Wood said the investigation into the crash is ongoing. “We’re still gathering facts,’’ Wood said.

The driver of the vehicle that struck Tarvin did stop at the scene. The chief said once the investigation is complete, they will present the findings to the district attorney’s office to determine whether any charges are warranted.
