Both father and son are in a hospital and police are trying to find out why it happened.
The gunfire started Sunday afternoon with the boy's mother just a few feet away. Galveston sheriff's deputies were at the home off FM 2094 near Kemah for several hours piecing it all together.
"The son retrieved a 9 millimeter hand gun, shot the father at least once," said Sgt. Barry.
It happened as the father, Robert Muler, sat on the couch. Galveston sheriff's investigators say the 59-year-old was shot in the forehead.
"The 911 call was placed by the mother who, unfortunately witnessed the entire incident," Sgt. Barry said.
Investigators say her heartache only got worse when police responded. Her 16-year-old son threatened suicide and then shot himself in the head.
"They were trying to talk him out of dropping the weapon. He stepped out of the officer's view and then they heard one shot," Sgt. Barry said.
Both were flown to Memorial Hermann Hospital with critical injuries. Neighbors in the small community of Lazy Lane are sunned.
"It's a close-knit community and we just went through a hurricane and now we have to go through this," said Slade Zapp.
Meanwhile, investigators are trying to realize what brought on the tragedy.
"I understand that the father dearly loved his son," said Sgt. Barry.
At last word, both father and son were in critical condition. The son is a junior at Clear Creek Christian Academy.
