A Washington state woman was critically injured Sunday when her ex-boyfriend smashed into her car at over 50 mph, trapping them both inside their vehicles as responders raced to the scene, officials said.

The incident happened in the town of Parkland at about 9:40 a.m., after the 34-year-old woman was spotted by the man, who was not identified because he hasn't been formally charged, the Pierce County Sheriff's Department said in a news release

"The male suspect T-boned the female victim’s Honda at speeds estimated to be at least 50 mph, crushing the side of the vehicle and critically injuring the victim," police said.
