The key here is that they were on their way to Massachusetts to see some “friends.”
I was wondering about that. The murder weapon is also of interest. Two 19 year olds don’t take a gun or drugs to the airport, I don’t think. You could leave the gun behind, I suppose, but if trafficking narcotics through an airport, you better know what you’re doing. Or nothing at all. A drug buy gone wrong, preceding any of that? Maybe. But convincingly made to look like murder-suicide? Not buying it.
