Sandra Walker was able to visit with her husband Monday, Michelle Walker said.
The Walkers, of Duluth, were on their way to Callaway Gardens, where Sandra Walker was planning to run a 10K race, Michelle Walker said. Family members aren't sure why the Walkers had gotten off I-85 and were on Flat Shoals Road, but speculated the family may have planned to stop for a bathroom break.
Investigators have not yet determined what caused the other driver, 36-year-old Tamara Matthews, to veer into oncoming traffic. Matthews' son, Joshua Jenkins, died at the scene of the wreck, near the intersection with Harper Valley Drive, police said.
Sandra Walker, Matthews and five children were transported to various Atlanta-area hospitals after the wreck, according to the investigative report.
Matthews, who was also injured, has not yet been charged with the wreck, Cpl. Kay Lester with Fulton County police said Tuesday. She is expected to face charges of second-degree vehicular homicide, failure to maintain lane and a seat-belt violation, Lester said. More charges are expected following Glen Walker's death.
Matthews allegedly struck another vehicle after hitting the Walkers' van, but the driver in the third vehicle was not injured, according to police.
"It truly is a tragedy; it is the definition of a tragedy," Michelle Walker said of the crash.
Glen Walker was a loyal friend who always smiled and enjoyed playing a variety of sports, such as basketball, flag football and soccer, Michelle Walker said. He attended the University of Georgia after growing up in Norcross.
Family members have posted blog updates online with updates on the Walkers, and dozens of relatives and friends have offered their support, prayers and thoughts. The response shows how many lives the couple has touched, Michelle Walker said.
"This was very unfair," she said. "He was only 35, with two small kids. She turned 30 in the hospital."
