A St. Paul man was sentenced Thursday to more than 11 years in prison for his role in the fatal shooting of a teenager last year at St. Paul’s Indian Mounds Park.

Rayvion T. Brooks, 19, pleaded guilty in Ramsey County District Court to one count each of aiding and abetting attempted second-degree murder for the benefit of a gang and first-degree riot committed for the benefit of a gang. Several other counts, including three counts of aiding and abetting second-degree murder, were dismissed.

Ramsey County District Judge Leonardo Castro sentenced Brooks to a little over 11 years in prison for the first count and about six years for the second count. The sentences will run concurrently.

Brooks was among a group of rival gang members who argued at the park, leading to gunfire that killed Bobby D. Collins, 18, on April 17, 2016, as several people picnicked nearby.

Jurors convicted Glen Dale Acon, 33, earlier this month of all six counts against him, including two counts of second-degree murder. He is scheduled to be sentenced July 6.

According to the complaints filed against both: Brooks and his girlfriend were at the park when rival gang members approached them. Brooks was a member of the Forever After Money (FAM) gang, his girlfriend told police, and the other men accused him of stealing their gang’s name. Another man, not Collins, swung a tree branch at Brooks, and “the men took out guns and began shooting.”

The charges do not implicate Collins in any action that day.

Brooks was initially identified as the suspected shooter, but authorities later found that Acon, who brought the murder weapon to the scene, was more responsible. DNA on the gun’s trigger later matched with Acon, the charges said.

“After obtaining both DNA and ballistics evidence from investigators in July 2016, we revised the theory of our case and determined that Glen Acon was culpable,” said Ramsey County attorney spokesman Dennis Gerhardstein.
