The family of a slain Ohio dentist and his wife have downplayed the significance of a shadowy figure seen on surveillance video the night of their mysterious killings, with police still not announcing a suspect in the crime.

Dentist Spencer Tepe and his wife, Monique, were found dead in their home north of Columbus, Ohio, on Dec. 30, with no signs of forced entry.

They had each been shot, but no firearm was found at the scene, and their two children and pet dog were unharmed.

Police on Monday released footage of a “person of interest” wearing a hooded jacket in an alley close to their home during the 2 a.m. to 5 a.m. window when the shootings were believed to have taken place.

However, Spencer’s brother-in-law poured cold water on the importance of the figure.

“I do think, you know, (it’s a) suspicious-looking person there. It also very well could be … somebody walking home drunk from a bar,” Rob Misleh, who is looking after the couple’s young children, told NewsNation.

He added that the couple, who were “so well liked and admired by everyone,” had no known enemies.

“They were always smiling, they were always laughing. So, it’s really just unbelievable and shocking to all of us when we found out. Still, a week later, it doesn’t, still doesn’t feel real. I can’t believe I’m, like, here talking about this,” he said.
