KANSAS CITY, Mo. -- There are new developments in a crash on I-435 that left five people dead, including three children. A semi plowed into the back of a car stalled red Mazda Protégé in a driving lane last December.

The crash killed Dominique Johnson, 17, Shante Hopkins, 24, and her three children, JaRiah Hutchison, two, JaNijah Hutchison, one, and seven-month-old Taeshawn Hutchison. The driver of the semi was not injured.

The KCPD report blames both drivers. The report gives new details about the crash--but also leaves questions.

Fighting back tears, loved ones of the driver Shante Hopkins told us in December that they wanted answers, particularly from the truck driver.

"Tell them you'll take a lie detector test and say that you wasn't texting, or you wasn't going to sleep behind the wheel," said Ricardo Smith.

"I don't understand how he couldn't have seen them, it was daytime," said Paulette Kelley.

Neither did investigators apparently as they determined that lighting and weather were not factors. Also, that driver had anywhere from 17-to 25 seconds to see Hopkins' car, and either brake or avoid it, but didn't.

Traffic investigators determined he was going 66 miles per hour in a 65 miles hour zone when the crash happened. The report also found Hopkins' car was stopped in the outside, southbound lane, but that she had plenty of shoulder to pull her car over.

Investigators couldn't explain why the car malfunctioned or if it was out of gas, or why Hopkins didn't get off the highway. Investigators found no problems with the truck's brakes or any other mechanical issues.

The report says the truck driver passed a field sobriety test and was not impaired. An autopsy found cocaine metabolite in Hopkins' system, but the report didn't say that was a crash cause. In fact, in the end the lead investigator concluded that actions on part of both drivers contributed to the cause of this collision.

We reached out to family members of both Hopkins, her passenger, and Dominique Johnson. They declined to comment to Fox 4 on the findings.
