A second arrest is expected to be announced Thursday in last year’s shooting death of 22-month-old Aiden Michael McClendon, caught in the crossfire of an ongoing gang war as he sat in a car with family in front of their Jacksonville home.

The Sheriff’s Office said it is having a news conference Thursday on 10 arrests in a year-long investigation of a criminal street gang.

Kquame Riquan Richardson, 18, of 10th Street South in Jacksonville Beach was arrested March 29 on a Duval County warrant in Okaloosa County, according to Duval County court records. He was booked into the Duval County jail the next day and remains there on one charge of murder, two of attempted murder, plus shooting into a vehicle and discharging a firearm from a vehicle. Richardson, whose arrest had not been announced by the Sheriff’s Office, faces a pretrial hearing Nov. 29.

On Jan. 29, 2016, police were sent to a Spearing Street home just after 6 p.m. on reports of shots fired. Aiden had been shot at least three times while in the parked car with his mother and great-grandmother. The gunfire came from a white Toyota Corolla that fled the scene, police said.

Family members told the Times-Union that Aiden was being brought home from the Head Start program when shots pelted their car. Bullets also hit the home.

It was determined to be gang-related, apparently part of a dispute between the Out East and Problem Child Entertainment gangs. The intended target was Aiden’s cousin, of the Out East gang, who in the front yard, police previously said.

Aiden’s family members made a public plea for people to step forward with information in the case. On March 10, police said Henry “Cracka Jack” Lee Hayes IV, 17, of West 43rd Street was under arrest on multiple charges including murder in the toddler’s death. Hayes also received a new charge this month of violation of RICO and conspiracy, court files show.
