Family of American Killed in London Found Out He Was Involved After Looking at Photos Online: 'We Miss Him'

Kurt Cochran was one four people killed when Khalid Masood drove an SUV into the crowded Westminster Bridge last week.

The family of the Utah man killed in last week’s London terror attack are determined to stay positive and focus on the legacy he left behind, saying they know that’s what their lost loved one would want them to do.

Kurt Cochran was one four people killed when Khalid Masood drove an SUV into the crowded Westminster Bridge and crashing into a fence before stabbing an unarmed Metropolitan Police constable to death near the Houses of Parliament last Wednesday.

Masood was then shot dead by an armed police officer.

Cochran was knocked off the bridge onto a concrete underpass 20 feet below.

"The most difficult part of all of this is that Kurt is no longer with us, and we miss him terribly," Cochran’s brother-in-law, Clint Payne, told reporters at a press conference Monday.

He and 10 other relatives traveled to London to be with Cochran’s wife, Melissa, as she recovered from injuries sustained in the attack, including a broken leg and rib, and mourned her husband.

"Right now, she is just trying to focus on healing herself and getting to the point where she can be healed and be able to return home,” Cochran’s sister-in-law Shantell Payne said.

Immediately after the attack, a photo emerged of Melissa lying on the ground, bloodied and being tended to by another woman. The haunting image alerted her family to what had happened.  

“… [W]e got online and looked and realized that that was our loved ones and so that's how we found out,” Melissa’s father, Dimmon Payne, said.

The couple was celebrating their 25th wedding anniversary by traveling to Europe, and was on the last leg of their trip when Cochran was killed.

Though devastated by the sudden loss, Cochran’s family said they are trying to remain positive and remember him for the amazing man he was.

"Last night we were speaking as a family about all this and it was unanimous that none of us harbor any ill will or harsh feelings towards this," Sarah McFarland, Melissa’s sister, said. "So we love our brother, we love what he brought to the world and we feel like that this situation is going to bring many good things to the world."

Clint Payne agreed, saying, "He was an amazing individual who loved everyone and tried to make the world a better place. He left a legacy of generosity and service that continues to inspire us. We are deeply saddened to lose him but are grateful that the world is coming to know him."
