I don’t want to say it was the vaxx but.......
but without ever knowing this person or having access to their medical records you’ll shoot your mouth off anyway.
Without access to reliable information, all one can do is bet the odds. And "the odds" themselves are a matter of assessment of incomplete and unreliable information.
Time generally reveals what is happening. We have had three years of fog and deliberate misinformation from authorities. A pattern has been established. Death rates from strokes in teenagers and twenty-somethings have increased dramatically in the last three years. They correlate strongly with receipt of the mRNA treatment.
Time-based correlations are very strong indicators of causation (but not absolute "proof"). Life is full of uncertainty.
I will say this death was caused by the "jab", unless proven otherwise.
I feel sorrow for the family who lost their teenager.
