Across the country on Friday, people showed support for Martin with marches and by wearing hoodies like Martin wore when he was killed last month by a neighborhood watchman. Many people are angry that the person who shot Martin has not been charged.
TSU's campus is just one of few places we will see community rallies filled with people demanding answers in the Martin case.
Lula Miller's hair salon in midtown for more than 40 years, and the 84-year-old stylist says she's seen and heard a lot.
"It's pretty hard for me to get angry about something. I don't get angry too fast," Miller said.
But these days, Miller and her clients say they've been fired up and having heated discussions about the death of 17-year-old Trayvon Martin.
"If it was my son, I would want justice served," client Angela Collins said.
Martin's the unarmed teen who was shot and killed by neighborhood watchman George Zimmerman as the teen walked to his parent's home in a gated Florida suburb last month.
"It it made me cry a whole lot about that," Miller said.
Zimmerman's claims he shot Martin in self defense have sparked outrage. Now many people across the country and right here in Houston are demanding answers about the way the Florida investigation was handled.
"It doesn't look right for a young, 17-year old boy walking home to be approached and to end up losing his life, and there not be what appears to be -- and should be -- a thorough investigation," Congressman Al Green said.
At a news conference in Houston, Green wore a hooded sweatshirt. It's a symbol of what the unarmed teen was wearing when he was shot to death last month.
And it's what some students at TSU have been wearing all week as they prepare for a Trayvon Martin rally on campus Monday.
"You know it's the pursuit of justice. It's not about color, it's not about race. It's the simple fact that, you know a situation happened, and the truth hasn't been told," TSU student G. Christopher Cutkelvin said.
And the truth is what many folks are calling for right now.
The community rally on TSU's campus will be 3pm Monday. It starts in front of the student center.
Another rally will be held 6:30pm Sunday night. Community activist Quannell X will lead the prayer vigil and community rally at Emancipation Park. Houston rappers Bun-B and Slim Thugg will attend the event.
Also on Sunday, the Houston Unites for Justice event happens at 3pm at City Hall's Reflection Pool, 901 Bagby Street, in downtown Houston. That event is organized by the NAACP-Houston Branch and is part of a national movement calling for the arrest of Zimmerman and a thorough investigation of Sanford PD.
