No, but the First shot of the Revolution was not at Lexington & Concord in MA.
It was the December prior at New Castle, New Hampshire
Prescott and other men broke into the fort and stole munitions killing a British soldier in the process.
This took place in December of 1774.
Five months before the shots at Lexington & Concord.
There is a Prescott Park today in the city of Portsmouth, NH.
The fort still stands on the same location in New Castle Island
There is now a Coast Guard base there.

It is a very short work, but important in highlighting that it was the first overt action against The Crown.
I don't believe anyone was killed though, but it was widely assumed with some personal account as evidence that the powder taken was one of the things being searched for in Concord, MA on April 19, 1775.
And that the powder was used against the British.
