Air Force Lt. Col. Melchizedek "Kato" Martinez is raising four children on his own following the death of his wife. "I find myself being a father for the first time after 18 years, because the truth of the matter is I've been gone so much," Martinez said. "I've been on missions and deployments because my wife allowed me to do that. She took care of the house. She was both mother and father."
While stationed in Europe, the Martinez family enjoyed making trips as a family to Disneyland Paris. The family of six was checking in for a flight to Orlando -- where they were planning to visit Disney World -- when the terrorist attack happened in March.
Martinez and his wife Gail pose for a photo on a family trip to Pisa, Italy. Gail's children say she had an eye for photography and was drawn to this orange wall, where the family took a series of portraits.
Kianni with her father. Their home is filled with photos of Gail Minglana Martinez -- Kianni's mother and Kato's wife -- who was killed in the airport bombing. "I don't want (my children) to ever wonder what their mother looked like," he said of the photos.
Kato sits with his children: from left, 13-year-old Kimo, 7-year-old Kialani, 9-year-old Noelani and Kianni. He says he doesn't want the Brussels terror attack to define his children's lives. "Their mother should define them."
Martinez hugs his son, Kimo, at the Center for the Intrepid, a military rehabilitation facility in San Antonio. Kimo sustained third-degree burns in the Brussels airport attack. The 13-year-old wants to study at the MIT and design high-performance cars.
Kianni works with trainer Troy Hopkins at the Center for the Intrepid. She was scheduled for a follow-up surgery on her left leg one day after this photo was taken.
Kianni is already following in her father's footsteps. The teenager is preparing for her university ROTC program, and she jokes that she wants to one day outrank her dad.
