I would say highly likely, especially if the killer was not Montoya or Blea, but rather a sex/drug ring run by/supported by APD personnel and local drug runners.. Is it coincidence the killings "seemed" to have stopped after Montoya was killed..? But at the same time, the time frame of the last girl(s) taken in the cluster seem to coincide with the paving/developing of that area of Dennis Chavez(I think that is what it's called)...Whether it's a killer or killers, they must have known that area would be hot very soon and couldn't keep using it...There has to be another cluster, maybe 2
so we have : 1)Montoya, 2)Blea, and some local sex workers(including one of the prior victims) strongly believing 3)police officer(s) are involved,either with/without help from a local drug cartel--that sounds a lot like the Jennings 8 scenario where it seems likely a local drug/sex boss and his drug minions along with police(or at least their complicity) carried out some killings(and in Jennings the vics were all tied together, like here it seems there might be some ties)...Maybe the MONTOYA agenda(or now Blea) was pushed by the APD to take heat off the possibility of an APD connection
