what ended up happening was Rich fought back and then ran when confronted by the armed men, and was subsequently shot in the back by the panicked MS-13 goons.

Rosati was supposedly on the scene, overseeing the whole debacle.

The whistleblower would go on to say that they would take the USB key and flee the scene because they had never intended to kill Rich in the first place, and in a moment of panic, a young man’s life was cut short.

This sounds like a load of horse shit. Seth Rich died in the hospital, after already being set to live, when the hospital staff / doctor over seeing him was swapped out. Then he was promptly killed in the hospital.
