HOUSTON – A collision involving a car and a minivan killed two people Monday in northwest Harris County, according to officials.
The crash was reported at 12:36 p.m. at the intersection of Grant Road and State Highway 249.
Video from a Houston Transtar camera showed one vehicle on top of the other. Both vehicles appeared to be upside-down.
 "It absolutely breaks my heart. It's senseless. Life is so short and so precious," witness Daniell Stegint said.Â
Investigators said a Honda Civic was traveling southbound on the feeder road when the driver lost control and hit the stopped minivan at a light.
"I had to pull over and see what had happened. This is just horrible," witness Jessica Mosher said.
Both vehicles flipped and the impact was so great, they were conjoined, investigators said.
Witnesses told KPRC 2 it took two tow trucks to pull the vehicles apart.
Officials said the two people who died in the crash were passengers of each vehicle. Police said a 19-year-old woman was ejected from the minivan and died.
Three other people were taken to a hospital in critical condition, officials said. One of those who was injured is a toddler and is expected to be OK, officials said.
"You can see the car seat strapped in properly and not squished at all so thank God, the baby survived," Mosher said.Â
Deputies are investigating what caused the Honda Civic driver to lose control, they don't believe alcohol was a factor.
"I had just been through here. That could have been me. That could be anybody," Stegint said. "It's senseless and it breaks my heart and it's just one of those things in life that we just never understand."
