The 20-year-old son of a Los Angeles Police Department (LAPD) captain has pleaded not guilty to felony charges related to an alleged armed robbery of a Westchester boutique, a Los Angeles County Superior Court spokeswoman said.

Kyle Bernard Jackson Jr., of Los Angeles, was arrested Tuesday, June 6th, along with another man and a woman, John Robeiro, 21, and Mallory Eddy, 20, both of Los Angeles, after they allegedly robbed the Jennifer Jeanne Boutique in the 8300 block of Lincoln Boulevard in Westchester, police said.

Jackson Jr. is the son of LAPD Captain Kyle Jackson, the commanding officer of the Robbery-Homicide Division, police said.

Police allege that the three suspects stole an unspecified amount of cash and jewelry from the boutique.

An off-duty Santa Monica police officer reported seeing Jackson Jr. and Robeiro allegedly run from the boutique at about 2:45 p.m. June 6th, and notified LAPD Pacific Community officers.

LAPD officers stopped the two men and Eddy in a vehicle at Riggs Place and Kentwood Court in Westchester, police said.

A handgun and other evidence were found in the vehicle, police alleged.

Jackson Jr. and Robeiro are charged with one count each of second-degree robbery and receiving stolen property.

They both pleaded not guilty to the felony charges Thursday, June 8th, a county superior court spokeswoman said.

Jackson Jr. also pleaded not guilty to an additional felony charge of preventing or dissuading a witness from reporting a crime, the spokeswoman said.

Eddy is charged with one count of receiving stolen property. Her arraignment is scheduled Wednesday, June 28th, at the superior court Airport Courthouse.
