"Our condolences, thoughts, and prayers go out to James' family, the other victims, their families and all who have been impacted by yesterday's events," principal Keith Richardson said in a statement Friday.

Mary Marshall, 34

Mary Marshall, a Navy veteran, was just weeks away from her wedding, which was set for Oct. 29, according to her sister.

"As a family we simply want to tell everyone how much of a joy and light Mary was. The most loyal and caring person," her family said in a statement. "She was one of the funniest people you'd ever meet. She was so excited to get married at the end of the month to Rob, the love of her life and best friend. And to finally have all her most favorite people in one place, including best friends from Japan, Texas and Florida."

The family begged local, state and national politicians "to finally step up and do something about gun control."

"Being a leader is about leading and making decisions that benefit, support and keep our country safe. How many times do we have to hear our leaders say 'we're sorry' and 'something must be done,'" the family said. "We demand action."

Nicole Connors, 52

Nicole Connors, who always looked out for her family, was shot while on her porch, her husband, Tracey Howard, told The Associated Press.

"Anything that had to be done, she was going to do it," told the AP. "And she was going to make sure it was done right."

"It is just a senseless killing," he told the AP. "People outside enjoying the weather, talking. Next thing you know they're gone."
