Chattanooga shooting victims
Four U.S. Marines and one sailor died as a result of an attack on a military recruiting center and another U.S. military site in Chattanooga, Tennessee, July 16, 2015.
The four Marines were killed at the scene. A Navy Petty Officer died July 18 from his injuries.
On the day of the shooting, President Obama called the deaths "a heartbreaking circumstance" to lose military personnel who served "with great valor."
Gunnery Sgt. Thomas J. Sullivan
Gunnery Sgt. Thomas J. Sullivan of Hampden, Massachusetts was deployed twice during the Iraq War and received two Purple Hearts. The Pentagon said he had been enlisted nearly 18 years.
His hometown mayor, Dominic Sarno, called him a man who "dedicated his life in brave service." Gov. Charlie Baker ordered flags to half-staff as he proclaimed, "Terror comes home to Massachusetts."
Lance Cpl. Squire K. Wells
Lance Cpl. Squire K. Wells of Cobb County, Georgia went by the nickname of "Skip," according to family spokesman Andy Kingery.
Wells hailed from the Atlanta area and was in his early 20s, when he was killed. He attended Georgia Southern University, but ultimately followed in his family's footsteps and enlisted in the armed forces.
Wells' long-time girlfriend, Caroline Dove, said Skip loved flag football, Nerf guns and U.S. history. She added that he had an uncanny ability to handle her when she was grouchy and was an extremely good listener. He dreamed of being a drill sergeant, she said.

Lance Cpl. Squire Wells was swapping text messages with his girlfriend of 2 1/2 years, just moments before he was shot. Wells was excited that she had booked a flight to visit him in Chattanooga after months apart.
"Can't wait anymore," Wells texted. "Yes you can honey," his girlfriend, Caroline Dove, replied.
His next two words would be the last she'd ever hear from him.
"ACTIVE SHOOTER," he wrote.
She thought he was kidding: "You are so weird," she replied.
Hours of silence. "I love you," she tried. Hours more passed, the news out of Chattanooga becoming clearer. "Hon, I need you to answer me please," she wrote.
She would not learn his fate until the next day.

Staff Sgt. David A. Wyatt
Tony Ward remembered Staff Sgt. David Wyatt as the young Boy Scout who would run up mountains, just for fun, seeking to best the time of others.
Ward, who now lives in Helena, Montana, was Wyatt's scoutmaster when he was in high school in Russellville, Arkansas. Wyatt and Ward's son were good friends and worked together at a Boy Scout camp. He said Wyatt attained the Eagle Scout rank and graduated from high school in 1991. He was married with young children, Ward said.
