Black Lives Matter St. Paul is planning a protest at the Twin Cities Marathon on Oct. 4, the group announced Friday.

The march and rally are in support of Tyree Tucker and his mother, Edna Waddle.

A St. Paul police officer is accused of using excessive force to arrest 15-year-old Tyree at a church picnic on Sunday. Waddle was arrested on suspicion of obstructing legal process, and the city attorney’s office is reviewing the case for potential charges.

The St. Paul Police Department is reviewing the case, and the St. Paul NAACP is launching its own inquiry into what happened during the arrest.

Next week’s rally is being dubbed Black Marathon. The group plans on “shutting down” the Twin Cities Marathon with their actions.

The rally will start at 10 a.m. in Boyd Park at 335 Selby Ave. in St. Paul.

“Black Marathon will disrupt, Black Marathon will bring awareness, Black Marathon will bring us closer to ending white supremacy and the institutions that enable it,” the group said in a statement.

Black Lives Matter organizers said they met with Police Chief Tom Smith, City Attorney Sammy Clark and Tyrone Tirrell, president of the African American Leadership Council, this week.

Group organizers called the meeting a baby step, but said it doesn’t erase what happened to Tyree or to Marcus Abrams, a St. Paul 17-year-old with Asperger’s syndrome who was forcefully arrested by Metro Transit officers on Aug. 31 at the Lexington Parkway light-rail station.

They also want answers about the death of 30-year-old Philip Quinn, who was shot Thursday by St. Paul police.

Last week, protesters from Black Lives Matter St. Paul halted light-rail service along much of the Green Line, blocking train traffic and shutting down a few major intersections ahead of the Vikings home opener.
