first things..sorry as well.
second..a similar thing happened to my parents house. their neighbors got robbed....2 houses adjacent... a week before this happened. they live out in the sticks, so its remote and no one would know if they killed her (mom) and threw her in the woods. (well, we'd know, but you know what i mean)
a week after all of the neighbors were hit, two men came up the gravel drive and my mom was the only one home. two dirty, trashy men...(probably had beards) ask my mom all sorts of questions....
do you own dogs, can we use the phone, how many acres...etc...
sounds to me like they are scoping the area. watching your daily routines to see when the best time is to take your things. these men did this for a month...they were caught and arrested....and thank god they didnt bash my moms teeth in with the butt of a pistola.
i'd be cautious..for real. chances are they are watching you more than you think.
