See footage of person of interest in killing of Ohio dentist and wife

Police in Columbus, Ohio, have released new footage of a person of interest in the shocking shooting deaths of a couple in their home on Dec. 30.

Spencer Tepe, 37, and Monique Tepe, 39, were found dead of apparent gunshot wounds on Dec. 30 after co-workers of Spencer, a local dentist, called police for a well-being check when he didn't show up for work, according to Columbus Police and The Columbus Dispatch, part of the USA TODAY Network.

The couple's two young children, ages 1 and 4, were unharmed in the home, police said. A Columbus police spokesperson told the Dispatch on Dec. 30 there were no indications a murder-suicide had occurred.

On the evening of Monday, Jan. 5, Columbus police released new details in the investigation, including footage of a person of interest walking near the Tepes' home, days after calling for the public's help in providing photos and videos from the area.

Meanwhile, the couple's loved ones are "heartbroken beyond words," the Tepe family wrote in a statement to USA TODAY on Jan. 2.
