On a GoFundMe page raising money for funeral expenses, Munoz’s brother called him “the king of this world.”
“All I want is for him to have a great journey with the huge amount of love that his friends and family will forever have for him,” Juan Camilo Munoz said.
It was not clear how investigators tied Betancourt to the case.
“Investigators from the fugitive unit located Betancourt and arrested him without incident in southeast Atlanta,” police said Tuesday.
Betancourt is being held on a murder charge at the Fulton County Jail.
