Mohammad Anwar, 66, of Springfield, Virginia, was killed Tuesday afternoon near Nationals Park, the Metropolitan Police Department said in a statement.
The girls, 13 and 15, assaulted Anwar with a Taser while carjacking him, which led to an accident in which he was fatally injured, police said.
The girls were charged with felony murder and armed carjacking, police said.
The younger girl is from the southeast section of DC, the older from Fort Washington, Maryland, police said.
Anwar immigrated from Pakistan in 2014, his family said on the GoFundMe page.
He “was a beloved husband, father, grandfather, uncle, and friend who always provided a smile when you needed one. He leaves behind a family, near and far, who cherish, love, and miss him dearly,” the family said.
