It certainly wouldn't be the first time a petty thief broke into the home of someone they knew to steal something they wanted. I don't know if I even believe that's what happened, but I suppose it's possible he (DS) figured he could sneak in, in the middle of the night and never be heard or caught.
Which brings me to my next thought: was TB scheduled to work the next day? The reason I ask is that I have to wonder, IF these 2 were on friendly terms and he (DS) was hanging out at Terry's house, he certainly wouldn't have been there at 3 in the morning if Terry was scheduled to work the next day. And another thought completely out of left field, based on the sudden change in Terry's life when Hailey was born (leaving behind the trouble and getting his act together) you wouldn't think he'd have anyone at his house, especially when Hailey was there, that might be a source of trouble. So if they were actually friends and not just aquaintences Terry must have not felt he (DS) was any kind of threat. So, what the heck was DS doing at Terry's house at 3 in the morning??
Just thinking out loud. FWIW.
