JACKSONVILLE, Fla. — A local community group hit the streets Saturday, demanding justice in the murder of a woman who was shot and killed while sitting outside her Jacksonville home in June.

At 66 years old, Cassandra Brown was gunned down on June 13 during a block party on Grothe Street, located on the city’s Mid-Westside. Police say more than 100 people were present that night—but so far, no arrests have been made.

Brown’s family told First Coast News they believe she may have been targeted for testifying in a shooting trial last year.

On Saturday, M.A.D. D.A.D.S. Jacksonville canvassed the neighborhood around Grothe Street, knocking on doors and urging residents to break their silence.

“We still can’t be scared to tell what we know,” said AJ Jordan, a representative of M.A.D. D.A.D.S. Jacksonville. “Now, if this person is still out here, that means he can kill somebody else.”

Jordan says the community’s silence is only adding to the family’s pain.

“We can’t be afraid to let the criminals rule our streets,” Jordan said. “We had a grandmother sitting out here on a chair just enjoying a nice Friday evening, listening to music, eating some honey dippers and things like that—and a coward came up and shot her.”

“So, I say to the community, there’s many different ways that we can get this information to the proper authorities,” said Jordan.

According to court documents obtained by First Coast News, Brown testified in a 2024 shooting case that also happened on Grothe Street. The defendant in that case was found guilty and sentenced to life in prison.

Now, some in the community fear her testimony may have made her a target. Friends are calling for stronger witness protection programs in the area.

“But, the girl reached out—she reached out two or three times and called the police and they ain’t do nothing,” said Roderick Dorsey, a friend of Brown. “So, how do you expect someone to help you? All you’re gonna do is take us downtown and put us in the interrogation room, and you ain’t still solve the problem.”

Deidra Vine, another close friend of Brown, said Brown was a beloved figure in the neighborhood—always ready to lend a helping hand.

“She was a good woman,” Vine said. “She was good to everybody in the neighborhood. You need something, she was there. If you needed a shoulder to cry on, she was there. If you didn’t have it, she had it. But, if you could look around now, she is gone. It ain’t like it used to be.”

Anyone with information about Brown’s killing is urged to contact the Jacksonville Sheriff’s Office or call Crime Stoppers to be anonymous.
