It's been almost 10 months since several masked people kicked in a door at the home of Little League coach John Brennan.
Brennan was shot dead, and his teenage son-pistol whipped.
And investigators still aren't certain why.
"Why did they pick this house? We don't know," Crimeline's Barb Bergin said.
The Orange County Sheriff's Office and Crimeline are now hoping you can help identify the suspects, who authorities say were captured on a neighbor's surveillance cameras just before and after the killing.
"We're looking for citizens that could help us identify why this house and why they were targeted," Bergin said.
About 4 a.m. July 18, deputies say the surveillance video shows five masked suspects in a light-colored sedan pull up to Brennan's home on Bridlewood Avenue.
Detectives note the time and date stamp on the video are off, but the suspects can be seen calmly walking toward Brennan's home.
Homicide investigators say the suspects then kicked in the door, shot Brennan and pistol-whipped his son.
Less than 3 minutes after entering the home, the suspects ran out. They took off after the one shot was fired.
They didn't take anything from the home, investigators say.
Brennan's son could only tell detectives that several black men were in the home.
Authorities are now circulating an image of the suspects' car.
Brennan, 50, was well-liked in his Union Park neighborhood in east Orange County.
"Does that video look similar to anything you've seen, and if it does, tell us how we can find it," Bergin said.
