"I just went in calling my wife's name and she never did answer," Robert Walker said.
About 30 minutes later, fire units responded to a blaze at Mary Brownlow's house a few blocks away. When the fire was extinguished, crews found her body in the smoldering wreckage. Lay said it was clearly arson.
At about 10:30 p.m., police responded to a report of a shooting at another home and found Wooden and Sluder dead. A 3-year-old boy in the home was unharmed and was released to relatives.
Tesla Savell, who lives across the street from the home where the two bodies were found, said worried friends sent her text messages as the slayings continued Monday night.
"It hits close to home," Savell said of the killings of the couple, whom she described as a "sweet family."
By this point, authorities had a description of the stolen vehicle Charles Brownlow was believed to be driving. An off-duty police officer saw that vehicle parked outside a convenience store at 10:37 p.m. As the officer called in the sighting, the suspect ran from the store, jumped in the vehicle and sped away, Lay said.
A high-speed police chase ensued. Charles Brownlow wrecked the car and took off on foot into thick woods, dropping a holster or handgun on the way, the chief said.
A police helicopter and dogs were summoned to assist in the manhunt, and Brownlow was found hiding in a creek.
Lay said Brownlow appeared to be intoxicated "on some sort of substance" when he was arrested.
The fifth victim, Leal-Carrillo, was a clerk at the convenience store. The store's owner, Ali Karimi, said he was a model employee and a "beautiful young man" who had a 1-year-old son.
