When it was over, Destiny had been shot in the elbow, Donald Coffey Sr. in the shoulder and Cammack, who was driving the Jeep, in the base of his skull. Little Donald Coffey, however, had been hit by several shotgun pellets in the face and head.
DeFoor said the two families gathered up their wounded into the SUV and raced to the nearest fire station about a mile away where medical helicopters and ambulances transported everyone to the hospital.
DeFoor said the investigation is ongoing, but police believe the Muhs may have fired as many as four shots from the 12-guage pump shotgun, each one spraying 15 pellets.
He called it "a total disregard for whoever may be out there."
Nelton declined to speak to ABCNews.com about the shooting, saying she's trying to take care of Cammack.
"We're all dealing with this very, very hard," she said.
She told the Houston Chronicle that she only had one wish for the Muhs. "They need to be dead," Nelton told the newspaper.
Gayle Muhs is being held on $25,000 bond for one count of assault, and Sheila Muhs, who faces two counts of aggravated assault, is being held on a $525,000 bond. DeFoor said the Sheriff's Office would be submitting further information to the district attorney's office today and expects the charges to be upgraded to murder.
Stephen Taylor, the court-appointed attorney for Sheila Muhs said he had not yet spoken to his client but probably would do so tonight.
"I don't know anything more than what I've read in the newspapers," he said.
The court said Gayle Muhs did not yet have a lawyer.
Though Donald Coffey Jr. was pronounced dead, DeFoor said his family had kept the boy on life support while doctors prepared to transplant his organs.
Cammack, he said, had been released from the hospital, the pellet still lodged at the base of his skull. Destiny and Donald Coffey Sr. were also treated for their wounds, he said.
DeFoor said the Muhs were known to police and have previous arrests though neither he nor the court could say what the charges were or when.
Most of the people in the area own firearms, he said, saying that that specific neighborhood was at "lower socio-economic level."
Texas does have a "castle" law that allows property owners to shoot if someone is trespassing on their property at night. But that law, he said, does not apply in this case.
While guns may have been used to settle disputes in the 1800s, he said, Texas is "not the Wild West."
