Mohammad Anwar, 66, of Springfield, Virginia, was killed Tuesday afternoon near Nationals Park, the Metropolitan Police Department said in a statement.
The girls, ages 13 and 15, attacked Anwar with a taser gun while abducting him, leading to an accident in which he was fatally injured, police said.
The girls were charged with felony murder and armed carjacking, police said.
The smallest is from the southeastern section of DC, the largest from Fort Washington, Maryland, police said.
Anwar immigrated from Pakistan in 2014, his family said on the GoFundMe page.
He “was a loving husband, father, grandfather, uncle and friend who always provided a smile when you needed it. He leaves behind a family, near and far, who appreciates, loves and misses him very much,” the family said.
