Speculative timeline:
I think the RSO may have been able to get to Jaimee Mendez, as she feared, before the friend arrived.
He then went to where ever he may have left her.
On his way back, he first may have gotten rid of her items near Technology Way.
He then was said to have visited the mother of his daughter, around 10 pmish according to the RSO (not confirmed information). He may have gone there to clean up and deal with the aftermath of whatever happened, such as the scratches, stuff on his clothes, whatever he needed to do, to be clean.
Then after the Mendez family search began and they confronted him, he cleaned his van of evidence and got rid of the piece of carpeting and her shoes. Mrs. Mendez herself found these in dumpster near his house (confirmed in MSM by police sources).
He has, by his own words, as liars often mix the truth with their fictions “She was with me 30 minutes tops,” and that nobody can “hide a body so well in four hours so 700 people can’t find her." So given that he has provided the time it may have taken him to achieve this,
and as nobody has yet confirmed that she is dead other than the RSO, and nobody else has come up with how much time he may have had to hide the body, it is interesting and completely damning that he provided this information, the way I see it.

If he had had the time to go out to sea, then he may have not had her clothing, phone and ID to dump on his way back, so where ever he went to hide Jaimee Mendez would be someplace that would have Technology Way as a convenient dumping spot on the way back, once he hid her someplace else. I think he assumed then as he assumed now that his story would hold, but that once the Mendez were onto to him, cleaning out his van and getting rid of the carpeting and her shoes was done with limited movement and time, way after the fact.
So, what may need to be figured out is where he may have been before he dumped her things off Technology Way. Perhaps security camera footage from around the Salem and Lynn area caught him moving around in his van. Descriptions of his van moving around from the time Jaimee Mendez called to when he may have gone to his former mate's place may be key.
The other possibility is that he may have left her in a dumpster that he knew would be picked up, around there, as he has a background in garbage collection.
There are two cemeteries, one nearby in Lynn Woods and another one just off Jackson Pond, those may have been options for him. He did this all not late at night with nobody around. It was between the hours of 6 and 10 pm ish so there is a good chance he was seen moving around or caught on security cameras in the area. I don't think she is far, I don't think some drug syndicate did this. The chances of that are minuscule and fabricated only by RSO statements and rumors, completely disregarding the facts.
Every place in America has people buying drugs, paying for sex, these are common, not unique to Lynn. Any criminal or defense lawyer wants to cast doubt on the victim or the circumstances, it is in their interest to do so. It is not in the interest of communities to believe brazen criminals when it comes to a missing mother who has an autistic son and a family who has acted with such bravery, gumption, and love so quickly and effectively. Jaundiced eyes may be prepared to distance themselves from the victims do that. Good people who care and are committed to finding Jaimie Mendez, I'm certain won't miss a beat because of what the RSO has put out there to cast doubt on her.
