Sounds like the shooter knew the store clerk. Jilted lover? Or he could have been hired by someone else to take her out.

Not sure how you're dubbing all that in. There's nothing in the report even remotely suggesting the shooters knew the victim.

Per the data in the article, it sounds like the store clerk was an older female of Indian/Pakistani extraction, while the shooters (given the deafening roar of their ommitted races) were very likely 'aspiring rappers, on the verge of turning their lives around.'

I doubt the clerk had ever seen them before.

A while back, I read that the average sentence in Washington, DC for conviction of armed robbery was 5-1/2 years.

The average sentence in Washington, DC for the conviction for murder was 7-1/2 years.

If you are a thug, what is the cost/benefit ratio for eliminating all witnesses?
