In my experience of living in a town where drugs (and robberies tied to drugs) are a major problems, "meth heads" looking for items to steal, or for money, tend to break in during the day or during times when the house is empty. They are generally not looking to hurt anyone, they just want to rob the place. Taking on a hostage would be rare, too. They usually rob out of desperation (they've depleted their own funds and everyone else's around them) and want to get in and out as quickly as possible. Home invasions, where people are broken in on in the middle of the night, tend to be something else entirely. The fact that this happened so late, and that Jayme was taken, leads me to believe that this was more than just a few addicts looking to score.
