21-year old Angelo Martinez was leaving a Walmart store in Albuquerque, New Mexico, when he met a group of people entering the store.  An argument broke out between the groups, then someone in the group pulled out a gun and fired shots, hitting several cars in the parking lot and hitting Martinez.  Martinez later died from the wounds.

From an article:
Police say the 21-year-old was gunned down around 9 p.m. in a busy Walmart parking lot near Coors and Interstate 40 on Sunday. He died at the hospital.
Police were called to the Walmart at 2550 Coors NW after receiving calls about a fight.
While they were en route, callers reported that shots were fired and someone was hit.
Police haven’t said if the shooting happened inside or outside the store, but the victim’s father, Melvin Martinez, said witnesses told him the fight was in the doorway of the store. Angelo Martinez was walking in while another group was walking out and words were exchanged, Melvin Martinez said. The other group knocked off Angelo Martinez’s hat, then punches were thrown and someone shot him.
Melvin Martinez said the witnesses he talked to didn’t know if the two groups knew each other or if it was a random interaction. ....
There was still blood on the Walmart parking lot’s asphalt Monday morning and employees had blocked four parking spots with caution tape while they tried to get it cleaned up. A Walmart employee said two people came into the store Monday because their cars had been hit by bullets and they were trying to get reimbursed for the damage.
Albuquerque Police Department spokesman Tanner Tixier said nobody in the parking lot or store had a description of the suspect to give to police.
Walmart.  Save money.  Die faster.
