Sorry, I've got to think like a criminal for a minute...
"Hey! Let's go a couple of blocks from the house, go into a multi family dwelling where there are hundreds of apartments and people coming and going at all hours of the day and night, make a big red glow in the sky so people can see HEY! I'm committing a crime!"
Or...
Let's go a couple of blocks south, dispose of phones in the river where they will NEVER be found...
I don't even like to see a cell call mentioned in these threads because "it's unconfirmed information and only speculation".
Earlier reports put the handyman at around 20 something years old. He's 42.
How reliable is this unconfirmed information that we are receiving? It's not.
It's no different than the Judge show last night where they were discussing the Irwins dog and the guy made a comment "I'm sure the burglar wouldn't have walked up to the window banging pots and pans together to make sure the dogs were barking". Same applies to anything that would draw attention. I don't think the dumpster was neither a diversion nor a way to dispose of evidence. I own a fire restoration company and I specialize in restoration of fire damaged structures and I can show you where a whole house burned down, and in the middle of melted plastic I recovered cell phones in the room that totally burned, I was able to pry the plastic apart and see the green componant board. Why did I do this? The homeowner was disputing with his insurance company the brands of several items he had, and the only way to prove what he had was to go into electronic componants and provide numbers off of the chipsets that were located in the electronics. I did the same thing a few years back where a malfunctioning space heater caught a house on fire. I ended up with a pile of melted plastic and some metal coils and turned it into evidence for a defective product lawsuit.
Even if badly burned telephones were recovered in the dumpster/landfill, I can't even say law enforcement would have released that information to the public but I'm guessing they didn't based on more heat on DB or JI. I also believe they could have traced final pings to that location. I have a feeling LE is still waiting on phone records too, but once again it's insiden information and only speculation at this point.
