The brothers lived near the site of the shooting, in a tent with their mother under an on-ramp at 4th Avenue South and Edgar Martinez Way, according to court documents. The brothers are suspects in other robberies and homicides in 2015.

According to surveillance video taken on Jan. 30, the two older brothers told a police informant they were the primary shooters — one wielding a .45 caliber handgun and the other using a .22 caliber pistol. On Feb. 1, an informant assisted police and told detectives that the brothers had bragged about the shooting, and allegedly said that they went into The Jungle to recover $500 that one of the shooting victims owed their mother for a drug deal.

Jungle has been a problem for years and remains a “violent, lawless place”, according to @KCProsecutor.
