CAMDEN, NJ (CBS) — The life threatening cold weather had police officers knocking on doors in Camden Saturday morning. The program in its second year is called ‘operation guardian’ and focuses on checking on the elderly and others in frigid temps.

KYW Newsradio went along with the officers as they went door-to-door in North Camden and Kramer Hill section. The officers had a list of about 50 names of residents that might need to be checked in on. Officer Will Stuart said they’re keeping an eye on residents, making sure they’re safe and warm.

“Make sure that they have, basically that they have electricity, that they have heat going that they are not utilizing any kind of heating device that they shouldn’t,” officer Stuart said. “One of the big problems is carbon monoxide poising from space heaters or the use of generators.”

Officers knocked on Maria’s door, asking if she was warm inside.

“My house is warm,” Maria said. “Especially my dogs.”
