WASHINGTON (AP) - The District of Columbia is adopting Boston's city flag this weekend as a symbol of solidarity.

Mayor Vincent Gray announced Friday that Boston's flag will be flying over the city's Wilson Building this weekend after the Boston Marathon bombings.

The district is hosting the Nike Women's half marathon Sunday. Also, the Washington Capitals play the Boston Bruins on Saturday at the Verizon Center.

WASHINGTON (WUSA9) -- He is one of the last people to see Boston bombing suspect Tamarlan Tsarnaev alive, and he's now telling his story of how the two brothers carjacked him the night before younger brother Dzokhar was taken into custody. 

This 26-year-old Chinese entrepreneur told his story to Boston Globe reporter Eric Moskowitz, under the condition he is only referred to by his American nickname, Danny. 

The story starts off with Danny pulling over his Mercedes on a Boston street to answer a text. Moskowitz says, "They pull up immediately behind him, the older brother gets out, wraps on the window. Tamerlan sticks his hand in the window, opens it, and pulls a gun on him." 

What follows is a 90 minute wild carjacking ride. Tamarlan warns Danny, "Don't be stupid." He asks the Danny if he heard about the Boston Marathon bombings. When Danny says yes, Tamarlan confides, "I did that. And I just killed a policeman in Cambridge."

WASHINGTON (WUSA) -- Only on 9, we have a follow-up to an alarming report we first brought you two weeks ago about a local mother who feared for her daughter's safety-inside her DC public middle school.

The school in question is Shaw at Garnet-Patterson in Northwest, one of the facilities slated to be closed for good this summer. After that story aired, several teachers came forward to say they feared for their safety too.

Current and former teachers independently provided WUSA9 with nearly identical accounts of what life is like inside Shaw Middle School. Some have moved on and are happily teaching in other area school systems. All said they were afraid of retaliation from DCPS and asked us to disguise their identities. We warn you, some of the language is graphic.
