The man who allegedly fatally shot a 6-year-old in road rage incident brandished a gun days later, prosecutors say

The man accused of fatally shooting a child in a Southern California road rage incident last month has confessed and brandished his gun at another driver in a separate incident just days later, according to prosecutors.

Prosecutors outlined what led to 6-year-old Aiden Leos’ death in newly-filed court documents in the case, as well as the startling events that followed.

The details come a little more than a week after authorities announced the arrest of Marcus Anthony Eriz, 24, and Wynne Lee, 23, as suspects in the shooting.

In a bail motion obtained by CNN, prosecutors allege Eriz and Lee cut off Aiden’s mother, Joanna Cloonan, as she was driving him to kindergarten.

The motion says Lee was driving in the HOV lane behind her, veered out of the lane and sped in front of Cloonan’s car, “cutting them off, and almost hitting” her vehicle. Lee gestured a peace sign and continued driving.

A few miles down the road, when Cloonan was preparing to merge onto another freeway, she passed Lee’s vehicle.

“As she passed the Defendants in the Volkswagen, she was still angry about being cut off and she put up her middle finger at the two as she passed,” the motion says.

After changing lanes, Cloonan “heard a loud bang to the rear of her vehicle, and heard her little boy in the backseat say ‘Ow,'” according to the motion.

She immediately pulled over and saw that her son had a bleeding wound to his chest, the document says. Good Samaritans came to help her while she called 911.

The young child was pronounced dead at a hospital a short time later.

The motion says Eriz admitted to police he was in the vehicle driven by Lee and was angry after being “flipped off” by Cloonan, so “he grabbed his loaded Glock 17 9mm and racked a round.”

“He then rolled the passenger window down and took a shot at her vehicle,” it says.

Days later, the couple was again on the road, with Lee driving and Eriz as the passenger. A driver in a blue Tesla did something that made Eriz angry and he again took out his gun and “brandished it to the driver of the Tesla,” the motion says.

That driver told the couple he had called police and drove away.

A week after the child’s shooting, a coworker approached Eriz and told him their car looked like the one police were looking for, according to the motion.

“Eriz claims that at that time, he looked on the internet and saw the story about Aiden Leos’ death. He said he ‘immediately’ knew he was responsible for the boy’s death,” the motion says.

After telling Lee about Leos’ death, Eriz hid Lee’s car in a relative’s garage and the two did not drive it again, according to the motion. In early June, Eriz changed his appearance by shaving his “substantial beard” and began to wear his long hair back in a tie, the motion says.

In the filing, Deputy District Attorney Whitney Bokosky urged the court to hold Eriz without bail, calling him a danger to the public.

“He has shown that he cannot control his temper and he goes to extremes in the snap of a finger when he is angered,” she wrote.

Eriz has multiple weapons in his possession and his social media posts show that he is a “skilled shooter,” Bokosky added.

The pair is scheduled to be arraigned in the Orange County Superior Court on Friday at 12 p.m. ET, at which time the judge will reconsider bail.

It is unclear whether Eriz or Lee have secured legal counsel. CNN’s calls to the public defender’s office were not immediately returned.
