WASHINGTON — An elderly couple, as well as a 29-year-old, has died and one woman remains hospitalized in critical condition following a lightning strike near the White House on Thursday, officials said. 

In a press conference Thursday night, authorities explained that just after 6:50 p.m. officials received a call about the lightning strike in Lafayette Park involving multiple people. 

U.S. Secret Service agents and U.S. Park Police officers were standing nearby when the lightning strike happened and was able to help the victims until first responders arrived.

According to a tweet from DC Fire and EMS, the four people were at the park outside the White House when the lightning strike happened. Witnesses tell WUSA9 that the four people were standing under a tree when the lightning strike hit. 

The four people were taken to a nearby hospital for treatment. 

DC Police told WUSA9 Friday morning a couple visiting from Janesville, Wisconsin died at the hospital. The couple was identified James Mueller, 76, and Donna Mueller, 75, of Janesville, Wisconsin. 

The couple from Wisconsin were visiting the district to celebrate their wedding anniversary. 

Police confirmed a third victim, identified as 29-year-old Brooks A. Lambertson, of Los Angeles, CA , died Friday. The fourth victim remains in the hospital. 

Brooks was a vice president at City National Bank, managing sponsorships for the company, and was in D.C. or business.

"Brooks was an incredible young man who will be remembered for his generosity, kindness and unwavering positivity. His sudden loss is devastating for all who knew him, and his family, friends and colleagues appreciate the thoughts and prayers that have poured in from around the country," a spokesperson at the bank said.

"We are saddened by the tragic loss of life after the lightning strike in Lafayette Park," White House Press Secretary Karine Jean-Pierre said in a statement. "Our hearts are with the families who lost loved ones, and we are praying for those still fighting for their lives."
