NEW YORK (CBSNewYork) — The mother of Kimani Gray, the teenager who was shot and killed by police in Brooklyn earlier this month, met with prosecutors Tuesday in hopes of getting answers about the shooting.

But as 1010 WINS’ Al Jones reported, after meeting with Brooklyn District Attorney Charles Hynes and other prosecutors at the office on Jay Street, Carol Gray left feeling frustrated at the lack of progress in the investigation into the killing of her 16-year-old son.

“It wasn’t surprising, and that’s why we want an independent investigation,” Carol Gray said. “It wasn’t surprising at all.”

Kimani Gray was shot and killed on March 9, by two officers in East Flatbush. The shooting has triggered protests that have at times turned violent.

“Our community is a powder keg. Don’t blame us if there’s an explosion. People are fed up,” said City Councilman Charles Barron (D-42nd).

Barron said the quickest way to defuse the situation is through justice.

Carol Gray said her son was killed in front of his best friend’s house after a birthday party. Autopsy results showed he was shot seven times in his shoulders, arms and legs, with wounds to the front and back of his body.

But police said Gray was with a group of young men that night, standing in front of a home on East 52nd Street when the officers, from the Brooklyn South Anti-Crime Patrol, approached.

When the officers started to talk to the group, Gray began acting suspiciously, police said.

Police said at one point, Gray grabbed for something in his waistband. Gray then pulled out a gun and pointed it at the officers, according to police.

When the plainclothes officers saw the gun, they both fired, police said. Gray was pronounced dead at Kings County Hospital a short time later, police said.

Protests against police actions in the case were held every night last week, from Monday through Thursday. Some of the protests led to violence and dozens of arrests.

Protesters have also appeared beyond East Flatbush. This past Friday afternoon, a woman addressed riders of the No. 1 line subway in uptown Manhattan, saying East Flatbush was under “martial law,” and accusing police of “murdering” Kimani Gray.
