Crime Stoppers: 2020 murder of Bernell Trammell's remains unsolved

MILWAUKEE (CBS 58) -- Bernell Trammell's murder rocked the community and made national headlines when it happened.

It even motivated former President Donald Trump supporters from out of state to put a large reward through Milwaukee Crime Stoppers. 

That made a lot of people call in and flood the tip line with information, but none of the tips were enough to close the case. 

Milwaukee police say surveillance video from July 23, 2020 shows the suspect fully covered from head to toe, riding his bicycle to go kill Trammell. 

"This was premeditated," said Milwaukee Police Department Detective Vincent Lopez III. 

The video shows the suspect, off his bike, walking over to the small business Trammell owned on Bremen and Wright -- holding a gun in his right hand. 

"He didn't even say anything to him that we know of the victim was facing south in his chair, the suspect arrived and from about 8-10 feet away, just started firing a gun right in the back of the victim and then he ran off, got on his bicycle and left the area. 

Trammell was known around Riverwest for sitting outside of his business expressing his political and religious views. Detectives believe that's why the suspect killed him four months before the nation's intense presidential election. 

"He was Pro Trump. He voiced it, he had signs up," said Detective Lopez. 

Trump supporters donate a $20,000 reward to Milwaukee Crime Stoppers but took half of it back when the case turned cold. 

"This man was executed and for just this viewpoint. It just boggles me, and I just feel like we just need to solve this case," said Lopez. 

If you recognize the man's body shape, clothes, his walk, shoes, or even how he swerves while bike riding -- call in a tip and you can still get a $10,000 reward if he's arrested. 

"Our victim, Mr. Bernell Tramell, he was just speaking his mind, his opinion which we all have that right to do, he lived in the Riverwest neighborhood," Lopez said. 

If you live in Riverwest, take note: 

"The way this person came to the area and left the area, I believe he lives somewhere in that Riverwest neighborhood. This could be somebody's neighbor," said Lopez. 

If you have any information about this case, you're urged to call Milwaukee Crime Stoppers at 414-224-8477 or use the P3 Tips App on your phone. No one will ever know who you are or be able to find you.
