London CNN  — 

The four people killed in the London terror attack included a veteran policeman, a teacher and an American tourist.

Kurt Cochran, who was visiting London from Utah with his wife, died as a result of injuries sustained in the attack, his family and church said. He was in his mid-50s, according to police.

British national Aysha Frade, a 43-year old teacher, was identified as another victim.

And Keith Palmer, a 48-year-old father and husband, was the unarmed police officer on duty at the gates of Parliament when the attacker stabbed him to death.

A fourth person, a 75-year-old man, died late Thursday from injuries, according to Metropolitan Police.

A wedding anniversary

Kurt Cochran and his wife, Melissa, were visiting London to celebrate their 25th wedding anniversary when, police say, Khalid Masood drove a vehicle into people walking along Westminster Bridge.

Cochran’s death was confirmed by family members and his church.

His wife, Melissa Cochran, suffered a broken leg, a broken rib and a cut to her head, but she will recover from her injuries, her brother Clint Payne said in a message on social media.

“Our hearts are broken this day as we say goodbye to our dear brother-in-law Kurt. He passed away from the injuries sustained in the London terrorist attack yesterday. We love him so much and will never forget him.”

Payne said he was grateful his sister would recover.

“Our hearts ache for her and their children in losing their loving companion and father. Please continue to pray for our family. Thank you.”

The couple ran the Onion Street Studio – a recording studio – in West Bountiful, near Salt Lake City, Utah.

Nate Kizerian, a close friend, said Kurt was passionate about music.

“I love talking to people that light up when they talk about what they are passionate about,” said Kizerian. “Kurt was one of those people.”

Kurt also lit up around the other love of his life: his wife.

“That’s what is bothering me the most,” said Kizerian. “They just celebrated 25 years.”

‘Every inch a hero’

Keith Palmer died at the scene.

After Officer Keith Palmer was stabbed, bystanders rushed to his aid. As he lay bleeding on the cobblestone street, Conservative MP Tobias Ellwood gave him mouth-to-mouth resuscitation, to no avail.

Tributes poured in from his family and colleagues, as well as the country’s leaders.

“He was a husband and a father, killed doing a job he loved. He was every inch a hero, and his actions will never be forgotten,” Prime Minister Theresa May said in Parliament.
