A veteran FBI special agent and attorney says only one person being seen on the street in freezing temperatures hours before Spencer and Monique Tepe’s deaths could benefit investigators.

“It was very, very, cold in Ohio that night,” Bobby Chacon told “Banfield” in an appearance Tuesday. “Nobody was out at 2 a.m. in that kind of weather. And so there was probably nobody else on the street.”

Columbus police released a new video recorded in the middle of the night Dec. 30 showing a person of interest walking in an alley near the home of the Tepes. The person described in the video was wearing light-colored pants and a hooded dark jacket.

Authorities discovered the Tepes’ bodies after several 911 calls from colleagues and loved ones hours later. Spencer Tepe’s co-workers notified police that he’d not shown up to work and Monique Tepe was not answering her phone.

Investigators said the couple appeared to have been shot after shell casings were found in the home. The couple’s two kids were found safe in a different room from their parents’ bodies.

“We know we have one victim with multiple gunshot wounds,” Chacon noted. “It sounds like we have a second victim with just one possible, so you want to know the sequence that may lead to and marry that with … forensic crime scene stuff.”

Officials say police are treating the case as a homicide and have ruled out the incident as a murder-suicide.

911 call months before killings shows woman was distressed: FBI agent

Police released a 911 call from the Tepes’ home months before Spencer and Monique’s deaths, in which a woman reported to the dispatcher what was described as a domestic dispute.

“Obviously, she was distressed enough to call 911, so at that moment that she’s calling 911, she was in fear of being harmed, because that’s why you call 911 in those types of situations,” Chacon said.

Records showed that the caller told the dispatcher, “Me and my man got into it.”

“Everything we’ve seen seems like the perfect American family,” Chacon added. “They’re happy, they’re successful, two young children. But, you and I both have seen cases where that on the surface looks like one thing, and below is another thing.”
