Kenny Lee said police had told him they caught two of the suspects accused in the robbery and shooting of employee Matthew Christensen.
Through the course of this investigation, Las Vegas homicide detectives identified 22-year-old Ray Brown and 20-year-old Lee Dominic Sykes as the suspects.
On Tuesday, both Brown and Sykes were taken into custody without incident. Both suspects will be booked into the Clark County Detention Center on charges to include murder with a deadly weapon.
Detectives are attempting to locate a person of interest in this case. The subject is identified as Lee Murry Sykes. He is 22 years old and is described as a black male adult, standing approximately 6 feet tall and having a thin build.
Christensen's brother Reggie felt "pretty good" about the arrests, which came on what would have been Matthew's 25th birthday.
"One of the suspects is the actual shooter," Reggie said.
He's relieved but also frustrated.
"Kind of difficult because Metro PD just chose to keep us out of the loop," Reggie said.
According to Reggie, Lee's called the family about the arrests, not police.
But he is glad the surveillance video of the suspects helped track them down.
"We're glad they caught two suspects and we hope they continue to catch the third one and get all of them put in jail and serve justice and hopefully get the death penalty."
Christensen's girlfriend Yvette Rioux said "they need to pay for what they did."
