Editor's Note: NBC11 reporter Damian Trujillo will be filing blogs from Mexico, as part of his investigation into the death of the woman known as the "Castro Valley Jane Doe." Follow his journey here, including Day 1 of his blog.

The last few days have been quite remarkable.

Detectives from the Alameda County Sheriff´s Office brought four thousand fliers with them. They've been passing them out in the main square in the town of Yahualica.

And Thursday, they visited several schools, and held informal assemblies with the student bodies, hoping someone will recognize Castro Valley Jane Doe, or the "person of interest."

The name of that "person of interest" is Miguel Angel Nunez Castaneda. He was a bus boy and dishwasher at the same Carrows Restaurant where detectives found the decomposed body of Jane Doe, in May of 2003.

Today, Thursday, I spoke with the younger brother of Castaneda. He is a student at one of the schools we visited. His eyes were watery, and he had a terrified look on his face. His name is Eric Nunez.

Eric told me his parents are extremely worried about the allegations. Nunez didn't want to do an on-camera interview, but says he feels terrible someone would do such a thing to a young lady like Castro Valley Jane Doe.

Detectives believe Jane Doe was either the girlfriend or wife of Nunez Castaneda, whom they believe she met in Nevada, and took her to the Bay Area.

I alerted the detectives that Castaneda's brother, Eric, did not mind talking to them, so the detectives interviewed him briefly... an interview our NBC11 cameraman Robert Wellington caught on tape.

The detectives are hopeful that the $65,000 reward will help them identify Castro Valley Jane Doe, and her family. Detectives say they will exhume Jane Doe's body from her resting place, and fly her home to Yahualica once her family is found.

Everyone here has been quite remarkable. We've received a police escort everywhere we've gone.

Wednesday was an exhausting day. After taking the red-eye from Oakland Airport, we began working immediately in Yahualica.

Rest didn't come until 9 p.m., and I welcomed the hours of rest, after the all-day-and-nighter. I welcomed the quiet time, even though the hotel where we're staying makes Motel 6 look like the Four Seasons, where hot water is taken for granted.

This is a trip I look forward to sharing with our NBC11 viewers.

We'll be back with deputies tonight (Thursday), and tomorrow, as they comb through this town of 35,000 people, two hours north of Guadalajara by car.

Wish us luck. The deputies have worked so hard for it.
