isn't the 13th (2 hour cell phone pings) around the time that he was called out by his boss and took off to Richmond for two hours?
just a rough timeline from this article:
25th of feb: she had reached five days out of school
26th fed: she is on video with Tatum
1 march last seen
2 march bought industrial trash bags
5 march: family meets with the school about her missing days
8 march relative says that tatum was in atlanta for some medical conference
10 march: school reaches out to this Dr. Tatum
13 march: relisha reaches threshold for reporting to dfs
13 march: tatum's cell phone pings in park <---- was her mother made aware of this or grandma? as they had Tatum's cell phone # from previous articles
19 march: social worker reaches out setting off string of alerts and police investigation they call tatum but it goes right to vm (he leaves work early and allegedly goes to Richmond)
20 march: body of Tatum's wife found in hotel

I wonder if his ex was living in that hotel and he just killed her there on that day (on or around)
