BOULDER, Colo. (CBS4) – Police in Boulder are thanking a dog for helping them with an investigation into a recent series of crimes.

Last Wednesday at 3:30 a.m. Squid, a Weimaraner/Pointer mix, woke up his owners in their Boulder home, located on Columbine Avenue.

“Squid started barking and growling, which is really unusual for him. He usually sleeps through the night,” said Squid’s owner Tina Fuller, who lives in the home with her fiance.

Squid led Fuller to her window, where she looked through the curtains and saw two burglars in the driveway breaking into her car.

“I saw two guys dressed in all black with a flashlight and bags over their shoulders,” Fuller told CBS4.

Fuller called 911, and police ended up capturing suspect Thomas Frampton, 23. Police say Frampton’s backpack contained several stolen items, including one of Fuller’s CDs from her car.

The other suspect escaped on what police say was a stolen bike and is still on the loose.

Fuller adopted Squid out of a Boulder animal rescue shelter five months ago.

“He had been chained up for three whole years, so he had no fur around his neck and he was very timid,” Fuller said.

Since then Fuller says the pet has blossomed, a fact the Boulder Police Department is happy about.

“Squid did a good thing. He helped us catch a bad guy,” spokeswoman Kim Kobel said.

Frampton now faces several charges, including trespassing and burglary, and police are investigating whether he may have had a role in other crimes.

“It’s possible that (the suspects) might also be connected to some other burglaries in that area,” said Boulder police spokeswoman Kim Kobel.

Fuller said they decided to name their dog Squid because they recently traveled to Asia and saw lots of squid and dogs and decided to marry the names.

“Squid was looking out for us. He’s got our backs,” Fuller said.
