A Fairborn High School and Wright State University graduate who deployed overseas as a civilian defense contractor in Afghanistan died of wounds in a non-combat related firearms incident, a NATO International Security Assistance Force spokesman said Tuesday.

Officials also say the incident does not appear to be a suicide.

Christina S. Maddock, 27, of Fairborn, died Sunday at Landstuhl Regional Medical Center, a U.S. military hospital in Germany, her employer reported Monday.

Maddock was employed as a field service representative with Colorado Springs, Colo.-based Intelligent Software Solutions, a software development and systems analysis company.

She was wounded Feb. 13 in the incident. Investigators do not have any indication the death was a suicide attempt, according to Army Maj. Adam N. Wojack, a spokesman at ISAF Joint Command in Kabul, Afghanistan. The military did not immediately release additional information on what happened. “The incident is under investigation,” Wojack said in an email.

Maddock deployed to Herat, Afghanistan, in mid-January as a field support representative with Intelligent Software Solutions in support of a one-year assignment with NATO International Security Assistance Force operations.

She was a 2003 Fairborn High School alumna and 2009 Wright State University graduate.

Funeral arrangements remained pending Monday, according to Melissa Burkett, an Intelligent Software Solutions spokeswoman.

“We’re very saddened by this event and we extend our deepest condolences to her family and the Fairborn community,” Burkett said in a telephone interview.

Maddock was in the same high school graduating class and in the same Air Force Junior Reserve Officer Training Corps unit at the school with Army Spec. Jesse A. Snow, who was killed in Afghanistan in November 2010, according to Maj. Tony Rulli, AFJROTC senior aerospace instructor in Fairborn.

“They were in the same classroom for more than a year,” Rulli said. “It’s a tragedy. It’s a shame for both of them.”

Snow was posthumously honored with the Silver Star medal for valor.

Those who knew Maddock said she was a cheerful person who easily attracted friends.

“Christina was a very excitable, happy-go-lucky type of person,” said Kameron T. Smith, a 23-year-old Wright State student from Fairborn. “She always had a big smile on her face.”

Maddock, a second lieutenant in the Ohio Air National Guard, earned a bachelor’s degree in mass communication and had a passion for media and service, said Kristin Sobolik, dean of WSU’s College of Liberal Arts.

Her death “shocked and saddened” the campus, Sobolik said.

“Many of our faculty and staff remember her very fondly as being somebody who was very engaged in the community here as well as somebody who would often times reach out and help other people,” Sobolik said.

Wright State’s Delta Tau Delta fraternity raised nearly $5,000 from donations to help defray the travel expenses of James “Jimmy” Maddock, Christina Maddock’s brother, and other family members, Smith said.

James Maddock is the president-elect of the fraternity.

“What we’re trying to do is just raising money for him and his family to be able to kind of ignore the financial burden that comes with this traumatic event,” Smith said.
