On Tuesday, Rick Eckhard, spokesperson for the St. Louis County Police Department, said Crockett was arrested in Hillsdale Monday night by Hillsdale police.
Crockett previously was identified as a person investigators wanted to talk to in connection to the shooting. Eckhard said charges have not yet been officially filed against Crockett, but they will be presented to prosecutors Tuesday.

Police are still looking for tips from the public.
"We believe four people are involved with this. Woods and three others. Right now, we only have the second person identified, Shermell Crockett. It's very possible there could be two more people involved, or not," Eckhard previously told Patch.
A press release sent out by Eckhard on Tuesday states that robbery appeared to be the motive for the shooting.
