(Jen Chung) The family of the woman run off a Bronx highway and then fatally stabbed by her ex-boyfriend said that the ex had been violent before. Katherine German's mother said, "He said he was going to kill her. He threatened to kill her twice."

Dionis Espinal, 31, was charged with murder, criminal possession of a weapon, and criminal contempt for the Wednesday morning rampage that spanned from the Paradise Motor Inn to the New England Thruway near Pelham Parkway. Espinal had apparently been spying on German, 20, the mother of his child (the Post says she had their baby two months ago), who emerged from the motel with her new boyfriend. Espinal got into his green outer-borough taxi and chased the couple to the highway.

Police Commissioner Kelly said, "He's driving up to 90 mph. He strikes the car that she is in, in the rear. The car tumbles over and he—that is the pursuing driver—gets out of the car." Police say that Espinal stabbed German through the window and hit her boyfriend, Jose Jimenez, with brass knuckles.
