Answer 1

The first one is Burglary Of an Inhabited Dwelling and maybe Simple Criminal Property Damage (Vandalism)- The UNAUTHORIZED entry of a dwelling used in whole or part as a home with the intent to commit a FELONY or theft therin.

The second one is Burglary, also. Because even though they didn't break in, they made an unauthorized entry and committed at theft.
