A deadly traffic crash in Lemon Grove created such force an engine block landed feet from the car, officials said.
One woman was killed when the Mazda3 she was driving westbound on State Route 94 left the freeway and hit a sign post. Investigators say she was going more than 100 mph and was not wearing a seatbelt.
The vehicle slammed into the metal pole signaling the College Avenue exit. Then, the car rolled down an embankment and landed at the bottom next to the chain-link fence.
The California Highway Patrol isn't sure if the woman was trying to exit College Ave and took the exit too fast, or if she lost control.
The car was damaged so badly, emergency personnel had to cut the car open to help her out.
The driver was the only person in the car, and died from her injuries shortly after the crash, CHP said.
She's been identified by officials only as a 21-year-old woman.
The cause of the crash remains under investigation to determine if alcohol and or drugs were a factor, CHP investigators said.
