See Motorcyclist Fleeing Ex-GF's Shooting Before Leading Cops on I-25 Chase

Just inside the door of a Northglenn home is this messsage:  "Welcome: May all who enter as guests leave as friends."

To put it mildly, what happened just after midnight yesterday morning violates this sentiment in a horrific way.

The woman who lived at the residence was shot, allegedly by her former boyfriend, who was caught on video leaving the scene on a motorcycle.

What followed was a high-speed chase, a crash, and a serious injury for the thus-far-unidentified suspect.

At around 12:16 a.m. on Monday, June 6, according to the Northglenn Police Department, officers were dispatched to a residence on the 500 block of East 116th Avenue.

The report: a burglary in progress.

However, that term hardly does justice to what was really going on.

According to the woman, her former boyfriend was trying to break into her home — and he had fired shots.

The cops raced to the scene, just missing the man, who split astride a black motorcycle — images captured in surveillance footage from a camera belonging to a homeowner just down the street and obtained by CBS4.

As emergency personnel helped the woman, who had been shot several times (a handgun was found at the scene), Northglenn officers pursued the motorcyclist.

The chase is said to have climbed into the triple digits.

It ended when the motorcyclist wiped out on the exit ramp from southbound Interstate 25 to 84th Avenue.

Both the suspect and his alleged victim were transported to area hospitals in serious condition.

Thus far, the Northglenn Police Department hasn't identified either.

But a spokesman tells CBS4 that the suspected shooter has a history of domestic violence and burglaries.

And it's believed that he committed each of these crimes yesterday morning.

Anyone with information about the crime is encouraged to contact Northglenn Detective Smith at 303-450-8980 or 303-450-8893.Continue to see the CBS4 report, complete with surveillance footage excerpts.
