ELKRIDGE, Md. — Charging documents reveal what led to a shooting on I-95 in Howard County Monday.
Investigators believe it's a case of workplace retaliation.
Around 4:30am Ronald Victor Garcia-Rodriguez called 911 reporting he'd been shot.
Maryland State Police found him wounded, walking along the northbound shoulder near the Prince George's County line.
Rodriguez told troopers he pulled over on the side of the interstate for a tire issue.
He claims a co-worker named Kevin Gross pulled up from behind in a Buick, stating "you must have hit a pot hole or something."
Rodriguez could see his tire was slashed.
That's when Gross pulled a gun, shooting Rodriguez seven times before fleeing.

Rodriguez felt Gross blamed him for being demoted at their job a day earlier.
Detectives tracked Gross' phone and Buick back to his home in Baltimore.
Later investigators conducting surveillance noticed Gross' location changed to his workplace at Planet Aid in Elkridge.
Troopers met Gross there and arrested him.
During an interview Gross admitted to showing up outside Rodriguez's apartment to "fight him."
When Rodriguez drove to work, Gross confessed to following him, but later said he changed his mind.
Cellphone records told a different story, placing Gross at the shooting scene before Rodriguez dialed 911.
Video footage also captured Gross hiding out in his Buick, while Rodriguez stopped at a BP gas station prior to the shooting.
Gross now finds himself facing attempted first degree murder and assault charges.
He's currently being held without bail. A preliminary hearing is scheduled for December 18.
Rodriguez was taken to Shock Trauma. There's no word on his condition.
Planet Aid President and CEO Fred Olsson said he was horrified to find out what happened to an employee.
Olsson says Planet Aid will be adding extra security and provide counseling services for its workers.
"Planet Aid was horrified to learn of this awful act of violence against one of our team. Our primary concern at this moment is the health and safety of our staff and the recovery of the victim to full health. We have engaged counseling experts to support any of our employees who were traumatized and, even though this crime took place away from work, we have taken additional steps to increase the physical security of all of our employees.”
