A 29-year-old man whose truck crashed through a glass wall at the Greeley Mall on Saturday, killing two women, has been released from the hospital, but the police are still investigating to see if charges will be filed.

The driver is an Evans resident, and his name hasn't been released. Police are saying now that neither alcohol nor drugs were involved, but the driver could have had a medical condition that caused him to lose control of his pickup truck.

Kimberly Fletcher, 32, of Greeley was a customer in the store and was hit and killed by the truck. Her husband, Tony Fletcher, was a security guard at the mall and was one of the first to respond to the crash. At the mall, Sunday, security guards wore black bands on their badges in support of Fletcher.

An employee of the store, Jennifer Hudgens, 23, died later at North Colorado Medical Center.

Hudgens was from Pueblo, and was a student at the University of Northern Colorado. Her father is a captain with the Pueblo Fire Department, according to Channel 9 news in Denver.

Fletcher's husband is reportedly a security guard at the mall, and their 9-year-old son was treated at North Colorado Medical Center and released. He suffered cuts from the flying glass in the crash. The boy's name hasn't been released.

Witnesses said it appeared the driver may have been unconscious behind the wheel just before the crash.

Police first reported the driver was 19, but now say he is 29 years old, from Evans.

Skid marks on the mall parking lot and between two barricades indicate the truck was accelerating when it crashed through the glass wall of Visionworks, a store next to the Greeley Mall theater.

Police said there was smoke coming from the store after the pickup crashed into the store. The smoke was likely from the tires on the truck, still spinning after it stopped against a wall in the store. Greeley Police Capt. Juan Cruz said that indicates the driver's foot was still pressed on the accelerator, even after the truck stopped.

Cruz said it seems unlikely that charges will be filed against the driver.

Although there are barricades in front of the mall, the truck passed between them. Police said the barricades are nine feet apart, and the truck didn't hit either one while traveling toward the storefront. It did graze a vehicle in the parking lot, causing minor damage.

Hudgens was a double major at UNC, in elementary education and physical education. Twice a week she student-taught this past school year at East Memorial Elementary School.

On her MySpace page, she said she loved her student-teaching experience, and in the future hoped to be endorsed overseas in teaching English as a Second Language.
