Mariska Hargitay Is 'Heartbroken' After Law & Order: SVU Crew Member Dies of Coronavirus at Age 45

Mariska Hargitay is in mourning after a Law & Order: SVU crew member died from the novel coronavirus (COVID-19).

The actress, 56, paid tribute to Josh Wallwork — a 45-year-old costumer for the NBC drama — in a tweet on Thursday, writing, “Heartbroken we are.”

“I don’t think I ever saw him without a smile on his face. He brought love and kindness everywhere he went. Always ready with the joke,” she remembered. “The SVU Corredor will never be the same. We will miss you Josh. #ForeverInOurHearts.”

The tragic news was initially shared by Law & Order: SVU showrunner Warren Leight, who tweeted a screenshot of a Facebook post from a Wallwork family friend announcing the death.

“Very sad news today. One of our costumers, and a beautiful man, Josh Wallwork, passed away from complications of Covd-19. Cast and crew send love and prayers to his family and friends. We are heartbroken,” he wrote.

You are loved by so many. As we always used to say, ‘Until next time, my love.’ ”

The first cases of a mysterious respiratory illness — what is now known as COVID-19, a form of coronavirus — began in Wuhan, China, in late December. Since then, the virus has spread worldwide, leading the World Health Organization to declare a public health emergency, the first since the zika epidemic in 2016.

At first, this coronavirus was contained to China, but Wuhan is a major transportation hub with hundreds of flights leaving from and landing in the city of 11 million each day. Soon, as people flew from the area, the coronavirus reached more countries, including the United States.
