Hundreds gather for funeral of slain Brooklyn activist Lavon Walker

CROWN HEIGHTS, Brooklyn — It was exactly one week ago on Sunday when Lavon Walker was sitting down and was gunned down in Miami.

Since then, police have found he was not the intended target of the shooting. It appears this man who loved peace was in the wrong place at the wrong time.

Mourners gathered for one last goodbye at First Baptist Church in Crown Heights.

"He was just a nice guy," friend Michael Wilson said.

The funeral was held for 30-year-old Walker on Sunday. Throughout the week, tributes were held for the man who fought to make Brooklyn's streets safer.

Tuesday evening, an emotional vigil was held in his honor on the footsteps of his non-profit of Save Our Streets (S.O.S.). Some could not hold back their tears.

"I would not be here if it weren't for Boo," one friend said.

Last Sunday morning in Miami Beach, Florida  – Walker became a shooting victim. Murdered while sitting with a group friends at a cafe.

Detectives say it was a well-orchestrated shooting except they got the wrong man. Tuesday morning, authorities took two people into custody but due to lack of evidence they were released.

The investigation is still active.
