I'm confused about Matias Romero Avendano because the full name of the stop is Matias Romero Avendano Sayula de Aleman,
Veracruz...not Oaxaca. Sayula de Aleman is where 185 meets 145D. I see the Matias Romero Avendano further south in Oaxaca on 185 also, but it's not in Veracruz.

Also, the Santa Maria full listing is Oaxaca Juchitan de Zaragoza- Sta Maria Guienagita 2674 which is just north of Juchitan, not out on that spit of land.

Apologies for not showing the actual maps. I'm terrible at that. But it appears to me that the truck left Sayula de Aleman in Veracruz at 11:30 a.m. which probably had it at Lagunas Crossing around 2:00 when I think Jenny was picked up IIRC. It wouldn't take until 7:15 p.m. to go to the address north of Juchitan I listed above. So whatever happened was between Lagunas crossing and north of Juchitan when the GPS started registering again.
I hope this makes sense. If I'm missing something about the place names, let me know.
