Catching up and no legal experience but found this Arrest Warrant so interesting because it is a very specific timeframe and thinking LE must know her exact attack time and exact death time because of the Fitbit giving heartrate beats. We know Mollie jogged with her cell phone in an armband and she likely had her Fitbit on.
It would be obvious from the Fitbit info the pulse rate when her pulse would suddenly go through the roof. Then when her heartbeat stopped altogether that is one way LE could know the exact time of death.
This is the first case where I have seen such a specific timeframe on the charges down to the minute.
The Fitbit info is the only way I can figure how LE knew this exact timeframe of the beginning of the attack and her ultimate death down to the minute.
On July 18, the attack began at 7:45 p.m. and the time of death was 8:28 p.m.
