You think I'm murdering someone with my (known) phone on me? Yeah, you definitely couldn't get away with it.
i didn't want to expound too much in that last post, but the cell phone thing is kind of a double edged sword for those looking to do a murder. Like if you have your phone with you then yeah, you are going to be in all the wrong places and will have some explaining to do. But if you leave it at home, the cops are gunna be like, huh, so for the window of time where this crime took place you (and your phone) were at home, using no data...didn't make a call or send a text or read gE or play candycrush or nothin for that entire time. And i mean yeah sure you can say you were taking a nap but the point is your sus lack of phone activity during the critical timeframe aint gunna get you off the suspect list.
I did see a dateline where the guy had his sidepiece come over and stay at his apartment all day, play on his phone, watch netflix, send text messages, while he drove (her car) 8 hours to go kill his estranged wife...even went to the trouble of filling up a couple of gas cans so that he wouldn't have to stop for gas and show up on some gas station surveillance video. But obvs that only would work if you had an accomplice willing to participate.
