Highly doubt it’s related. Ft. Worth is a large city, the 4th largest in Texas. And like most large cities, it’s got its rough areas. So while the city itself is pretty nice and fairly safe as far as large cities go, the East side is definitely not an area you want to be at any time of the day. That particular area off Rosedale and Lancaster and just west of Loop 820 is notorious for gang violence and armed robberies. It’s the kind of place you expect there to be at least one shooting per night. So while anything is possible, I would guess the shooting was nothing more than your garden variety armed robbery or drug dispute turned violent.
The scary thing about this crime is that, from where he took her, the perp could be on a major highway in a matter of just a few minutes and in another city very shortly after that. I-30, I-35, Loop 820, and even I-20 are all very close by and can have you in another city or even a short while later in another state pretty quickly.
