Chesterfield police hope the smallest clue can break the case of finding who shot little Brendon Mackey.
Bike patrol officers on foot near Sunday Park in Chesterfield are still very visible in the area where 7-year-old Brendon was killed by a stray bullet on July 4th.
"This case is particularly horrendous, because you have a very young child, minding his own business at a legitimate activity with his father, and now he's dead,” said CBS-6 crime expert Steve Neal. “I don't ever see a case like this going cold."
Police have gone door-to-door for a few weeks, knocking on thousands of doors in Brandermill to try and get information that will help them solve the mystery.
Monday they did more of that, even fanning out into the Harbour Point area to see if they could score some leads.
"It could be a situation where someone just found out about something and they may be able to tell police what happened,” said Neal. “Or you can have a change of circumstance, where there may be a domestic situation where someone may get mad at the offender and tell. It's wise for police to keep the pressure on."
Neal, with decades of experience in law enforcement, says in a case like the Mackey incident, you can expect police to pull out all the stops.
"It's going to cost a tremendous amount of resources to resolve this,” he said. “It's the nature of the case and their desire to solve it that drives the investigation, not the money that it will cost to complete it."
Remember police are looking for the owner of a .40 caliber weapon who fired it in the air July 4th. The bullet is a full metal jacket. Neal says police are looking in the right area. That is, the neighborhoods located close to Sunday Park.
