Detectives spent most of Sunday talking to eyewitnesses to try and figure out how the little boy ended up at the bottom of the pool at an apartment complex on Westheimer near Westerland.
It was mid-afternoon when Jay Jones heard a frantic knock on his door.
"She asked me, 'You seen Jonathan?'" Jones told us.
It was a mother looking for her young son. Jones went out to help look for the 3-year-old boy. First, he saw by the pool the ball that the boy loved. Then he spotted something at the bottom.
"He was laying face down at the bottom," said Jones.
Police say the pool was surrounded by a fence and a locked gate. The gate is about four feet tall. It's not clear how that little boy ended up alone inside the fence or how long he was alone in the water before he was found.
Jones helped pull him out and started CPR. Police, however, say it was too little, too late.
"I don't have no idea how he got in there," Jones said. "But you know kids, they find something, they find a way."
Police are still trying to determine just how this boy got inside the pool. His family says he wandered off for just a moment before his mother realized he was gone.
