"He or she needs to come forward ... so my son can rest," said Jayden Aguilar's mother, Kelly Holder. The five-year-old boy was killed after he and a two-year-old relative slid under a fence chasing a ball that had sailed over it onto Fallbrook Drive.
Original report: Two boys struck by car in N. Harris Co.
Jayden's uncle, Osbaldo Aguilar,was there with the boys playing catch last night.
When the boys ran into the roadway, a driver slammed into the two children. He says Jayden tried to push the younger boy out of the way. Osbaldo Aguilar says he tried to help, but it was too late.

"When I went back to Jayden, he was not breathing at all. That's when I realized that God had gained an angel," he said.
Two-year-old Jeremiah Aguilar was taken to Texas Children's Hospital. Osbaldo says Jeremiah has a broken leg, but is recovering.
A field of debris could be found near where little Jayden died. Parts of the suspect's vehicle strewn along the grass.
Family member Doris Aguilar says that driver carelessly drove off without stopping.

"Whoever caused this, if he has a heart, [he needs] to come forward," Aguilar says.
Deputies say they are looking for a dark-colored orange or red pickup or SUV, believed to be a Chevy Avalanche, according to a witness.
The vehicle would have some minor front-end damage, but deputies aren't certain the extent of the vehicle's damage.

Jayden is not the first child to be killed near Doss Park. Just yards away, five-year-old Nathaly Coreas was hit by a vehicle while walking home from the park in 2006. Her family convinced Harris County to add a stop light and crosswalk there. Now Jayden's family says something needs to be done to reinforce the fence between the park and traffic so no one else gets hurt or killed.
"There's a fence and they can get underneath it," said Jayden's mother Kelly Holder.
The county says this is an ongoing problem: people will cut the straps and ties that secure the bottom of the fence in order to make it easier to get in and out of the park, never realizing the danger they create by doing so.
Harris County Precinct 4 Commissioner Jack Cagle has asked parks staff for recommendations on making the fence more secure.
