After a road rage shooting that took the life of 6-year-old boy Aiden Leos in Southern California last month, the couple who was allegedly involved pleaded not guilty in court on Friday, June 18.

The suspects, identified as Marcus Anthony Eriz and his girlfriend Wynne Lee, appeared in the Orange County Superior Court virtually. 

Eriz pleaded not guilty to the charges of murder and shooting at an occupied vehicle that resulted in the death of Aiden Leos. On the other hand, Lee claimed that she was not guilty of the accessory charge and illegally carrying a concealed firearm.

Judge Revokes Bail for Marcus Anthony Eriz

According to ABC News, Judge Larry Yellin said that 24-year-old Eriz's behavior after the road rage incident made him a "complete danger to the community." Thus, he ordered that Eriz remains in jail without bail. 

Eriz's 23-year-old girlfriend was being held on a $500,000 bond. Lee is set to face the court again for another bail hearing on June 25 following a background evaluation that would look over where she will live and work after posting bail.

The California couple are scheduled for preliminary hearings on August 27.

What Happened in the Shooting That Killed Aiden Leos?

Last May 21, the 6-year-old boy was killed by gunfire while at the back of his mother's car during a ride on his way to kindergarten, Fox News reported.

Prosecutors noted that Leos' mother, Joanna Cloonan, was driving on the 55 Freeway in Orange County when the California couple cut her off. Prosecutors said that Cloonan allegedly put up her middle finger at the suspects after being cut off.

Afterwhich, the mother heard a loud bang and her son's "Ow." At that point, she looked back at her son and saw that he was bleeding from his chest. Aiden Leos was then rushed to a local hospital, where he died.

According to a court motion written by Whitney Bokosky, a prosecutor of Orange County, Eriz admitted that he was enraged after being flipped off by Cloonan.

When he was arrested on June 6, Eriz told investigators that it was the reason why he grabbed his Glock 17 9mm and fired shots.

Eriz further noted that he did not know that Leos died until a week after a co-worker told him that authorities were seeking a vehicle resembling his car due to the boy's death.

Suspect Involved in Another Road Rage Incident

Meanwhile, Marcus Anthony Eriz reportedly got into another incident of road rage just a week after the death of Leos. Prosecutors said he allegedly flashed a gun to a man who drove a Tesla vehicle, The New York Post reported.

Authorities reportedly found several firearms in Eriz's possession, including the Glock 17 9mm allegedly used in shooting Leos.

Aiden Leos' death gained national attention, and the reward for the suspect who shot him during the road rage incident reached $500,0000.
