good friend kory carico was with caleb. >> i took him back to my house and i was going to make him staybut he knew he had to get home. i knew that for sure. he kept bothering us about it, >> reporter: staggering now, caleb needs his sober friend to walk him the few blocks home to his quiet cul-de-sac where many of the houses in the development look nearly identical. >> we crossed this fence because all the houses are similar, and once we crossed we came up to this window over here. >> you thought this was the window? >> yes. we thought this was the window, and i just opened it up. i've never come in the back way before. it looks different from the back. i always come from the front when i come pick him up in the morning, so i figured it was his house because he thought it was his house, too. >> reporter: did you just sort of like shove caleb in? >> no, he went in himself. the alarm went off and then i saw the light come on and then i heard yelling, which i thought was his dad, so then i ran because i thought i was going to get in trouble. >> reporter: turns out it's not caleb's dad, in
