Though there is no information to confirm that the RSO works for waste management company in Revere, the low flying helicopter search over the area may indicate that LE is focused on the areas that the RSO may have been the night Jaimee Mendez vanished. The map below shows that it is a straight shot down the Salem Turnpike 107, from the Floating Bridge Pond, where LE sent divers and performed side sonar searches. It stands out that Jaimee's cell phone was found exactly in the opposite direction on Technology way. Though LE may not share what leads may have caused them to scan Revere, the fact that they have speaks volumes. It would be further confirmation that the search is solely focused on the movements of the RSO.
So, I'm hypothesizing that the RSO, after having brought Jaimee Mendez to harm, as she tried to escape from him to meet her friend, then drove out of his residential neighborhood, past the floating Bridge Pond where LE searched, and down to Revere, where LE scanned with helos, to dispose of Jaimee Mendez herself. He then drove to Technology Way to rid himself of her phone and other evidence closer to home to give cover to his story that local dealers in Lynn were involved and to not attract interest to areas he may be familiar with in Revere. He may have turned on her phone one last time to give the location information that caused LE to find Jaimee's things so quickly around Technology way.
The RSO may not have known, as he may have struggled with, killed and disposed of Jaimee Mendez, that her friends had been on to him before he returned to his home on Spring Road. Upon seeing and realizing that the friend and family were looking for Jaimee at or around his house, the RSO then went to his girlfriend's to give himself an alibi. When he finally did return to his home, Alyssa was there to confront him and spotted the scratches on his face and hands from the struggle he may have had with Jaimee. Upon realization that he would become of interest to LE and that they may search his van, which was like a bedroom one night, as seen by Steven Mendez, and cleaned up by the next day, he may have set himself to cleaning his van. That would mean that he then went about getting rid of the carpet by cutting out the piece that may have had evidence on it and getting rid of rest of his things in the van that may have had evidence on it. He did this knowing that the heat may have been on him soon. So he quickly went about dumping various parts of the material from his van as fast as he could in various dumpsters, which specifically would not lead back to Revere. LE upon finding the said evidence from his van and having it tested then had enough for probable cause to issue warrants to seize his vans and search his properties. The search as it progresses has since been focused as such. It seems to me, that by now, LE has had the cooperation of the friends she called for help, of any ancillary dealers or people that the RSO may have pointed out as involved, and that as such LE discounted their involvement and has stay focused on the RSO's movements as they investigate.
