A teenage suspect attempting to rob a Rodgers Forge man who was standing at the back of his car led to a struggle and shooting last month, according to police charging documents, as new details emerged in an incident that has shaken the tight-knit community.

The altercation left the victim, a 50-year-old man, critically wounded and led to the recent arrests of a 15-year-old and a 16-year-old, both of whom are being charged as adults with attempted first-degree murder, assault and related gun charges. The two teenagers fled in a stolen white Kia SUV, according to charging documents, which also detail how law enforcement used social media and cellphone data to find the suspects.

Surveillance footage obtained by Baltimore County Police shows the victim, identified by friends and a gofundme.com site as Mark McKenzie, cleaning the rear cargo area of his car on Sept. 13 when one of the teenagers, wearing a black sweatshirt with “distinctive markings” and the hood pulled up, approached him. McKenzie turned to see the suspect just as the 15-year-old raised a gun toward McKenzie’s head, according to court records.

The two struggled, then stumbled into a nearby alley, where the teenager fired one shot, striking the man, according to the documents. He fell to the ground.

Witnesses said they saw someone run from the alley to a waiting SUV, which police said was a Kia that had been reported stolen the previous night.

Additional video footage shows the two teenagers arriving at North Lakewood Avenue about 23 minutes after the shooting, police said, and then pouring bleach on the interior and door handles of the white SUV.

Detectives said they used social media and other cellphone data, including data obtained through a warrant with a mobile carrier, to find at least one of the suspects, court records show.

The attempted robbery and shooting come in a year in which lawmakers have been scrutinizing rules around juvenile justice, and as officials react to a violent attack on a 66-year-old man that was captured on video in Butchers Hill. Authorities have charged two males, ages 18 and 15, in that robbery and attack.

The shooting took place around 11:30 a.m. behind a home in the 400 block of Dunkirk Road, a leafy street lined with townhouses. Police said the victim was shot once and taken in critical condition to the hospital, where he underwent surgery.

Residents of the Rodgers Forge community rallied around the family of the victim, a beloved youth sports coach and father. A community walk was organized, and as of Friday about 1,300 people had contributed to a gofundme site that has raised more than $132,000 for the family.

By the time police announced the arrests, residents of that pocket of Rodgers Forge had decorated their lawns with bedazzled cobwebs, giant spiders and 8-foot ghouls.

Moms pushed their kids on strollers down the street Friday morning. Neighbors raked overgrown flora in their front yards. Any sign of a shooting in that quiet suburban stretch of Dunkirk Road faded to whispers between neighbors.

Some who spoke with The Baltimore Banner said they were still trying to figure out what happened on the day of the shooting. Minna Knight, who works as a video editor in a house on the same block where the shooting occurred, said she heard a “loud pop.”

Carol Ashmen, who lives a couple of blocks away, said she came upon a cluster of police cars in the alley as she walked her dog.

“At first when I heard of it, I thought, ‘I need to get a gun. I need so much protection,’ ” said Ashmen, who has lived in the area for 40 years. “But there’s always somebody working outside,” she said under the din of a neighbor’s lawnmower.

Ashmen still takes her doodle on daily walks near the alley.

“Hopefully,” Ashmen said, “it’s a one-off.”

Police said they had connected both teenagers to an armed robbery on an MTA bus on Sept. 11, where they allegedly had a victim send money via CashApp.
