On February 24, 2005 David Hernandez Arroyo Sr., 43, ambushed his ex-wife Maribel Estrada and their son David Hernandez Arroyo Jr., 23, outside of the Smith County Courthouse in Tyler Texas. Maribel was taking David to court over thousands in unpaid child support, David however had other ideas. Armed with an AK-47 clone David ambushed and shot his wife in the head, killing her, and shot his son in the leg, wounding him. A gun battle then ensured as officers inside the courthouse responded to the shooting outside, David however was wearing body armor and with his rifle he was able to easily keep the responding officers, many of whom only had handguns, at bay.
During the shooting a bystander with a a concealed carry permit and Colt 1911, Mark Alan Wilson, approaching David from behind. Seeing David aiming at his son, intent to kill him, Mark defended David's son by firing a round into David's back striking his body armor. David responded by redirecting his attention towards Mark firing several shots back at him. A brief firefight between the two ensued in which Mark was killed.
With more officers responding to the courthouse David decided to make his escape, by now more than 100 rounds had been fired by both sides. Climbing into his pickup truck David sped through the streets of Tyler, continuing to exchange gunfire with pursuing officers. Eventually a pursuing deputies, John Smith, managed to speed up and ram into David's truck. Intent on murdering the cop David exited his truck, weapon in hand, only to have John speed off, leaving David fully exposed to the responding law enforcement. A police sharpshooter, Rusty Jacks, then exited his patrol car with a Colt AR-15 and, taking aim, fired five at David, killing him instantly, this being captured on police dash cam (see below).
In total 3 people died during the shootout, David Hernandez Arroyo Sr. (the perpetrator), his ex-wife Maribel Estrada, and the intervening good Samaritan Mark Wilson. Four others were wounded, David Hernandez Arroyo Jr. and three law enforcement officers.
