739 died in one week from the heat and no one claimed some of the bodies.

Living in a different county, we were in the heat area and had the same type of temps - no A/C. Window fans were overmatched. The window A/C unit kept tripping the circuit breaker.
My daughter finally jumps off the couch and screams "Go buy Central a/c and figure out how to pay for it later." which we eventually did.
Same daughter now lives in Wichita Falls Texas.
Of Course, obviously, she has a/c and a large outdoor pool.
