Original Story on May 31, 2016: Authorities on Tuesday captured Marquez Billingsley, one of the state's "Top 10 most Wanted" fugitives and the 18-year-old Knoxville man wanted by local police for questioning in last month's gang-related shooting of a 12-year-old.
Officials with the Tennessee Bureau of Investigation said he was taken into custody in Chattanooga after TBI agents, officers with the Chattanooga Police Department and U.S. Marshals apprehended him during a traffic stop at the intersection of Dodds Avenue and East 23rd Street.
Police have spent weeks searching for Billingsley, who is wanted for questioning in the April 16 shooting of Jajuan Latham, who was shot to death as he sat in his father's vehicle at Danny Mayfield Park.
Earlier this month, state authorities placed him on their Top 10 list and Knoxville police announced their were felony warrants for aggravated robbery, aggravated assault and carjacking for his arrest.
"If he has some direct involvement in this shooting, the death of Jajuan Latham and this unborn child, then we'll certainly look forward to bringing charges at that point," said Knoxville Police Chief David Rausch.
Knoxville police said Billingsley was one of two men who held two other men at gunpoint with a MAC-10 gun. KPD said Billingsley and the man threatened to kill the two men if they did not give them their money and car keys.
Knoxville police said the victims emptied their pockets, which contained one dollar, a cell phone and car keys to a 2004 Saturn.
Authorities said Billingsley and the other man took the items and fled the scene in the Saturn.
At a press conference Tuesday afternoon, Rausch said there have been 17 shootings with victims since Dec. 17, 2015, the day Zaevion Dobson was killed. A majority of those shootings are the result of illegal activity. In 2016, there have been two gang-related homicides with three victims.
"We are working on cases right now to eliminate each and every one of you from our society to get you out of our community," Rausch said. "If you're a member of a gang, your choice is very simple-- give it up, or go to prison. It's a real simple choice."
