Police in Madison, New Jersey, are asking the public for help finding a 49-year-old man who vanished earlier this week, an effort that has drawn law enforcement from several nearby towns.
Cavan Londergan was last confirmed to be in Madison on Monday, August 3. He is described as a white male standing about five feet ten inches tall with a slim build, gray hair and blue eyes. At the time he was last seen, he was wearing a green T-shirt and khaki pants.
An emergency alert went out to phones across Madison Tuesday evening, just before 7 p.m., asking residents to keep an eye out for him and to report any information. Officials have not said what led up to his disappearance or whether they believe he is in danger.
Multiple Agencies Join the Search
Not long after the alert was sent, police cars from departments outside Madison began gathering near Madison High School, an indication that officers were preparing for an organized ground search.
Among the outside agencies seen responding was the Parsippany Police Department, suggesting the case has ties beyond Madison itself.
Local officials have not formally labeled this a joint search between multiple towns, but the number of agencies involved points to a coordinated response as investigators try to track Londergan’s movements and figure out where he might have gone.
Community and Family Ties
According to public records and social media, Londergan is married and has two sons. He has worked in education, and sources connected to the case say he serves as a guidance counselor at Parsippany High School, which may explain why officers from that town joined the response even though he went missing in Madison.
Neither Madison police nor school officials have released a statement addressing his role at the high school or how his disappearance might affect students or staff there. As of Tuesday night, authorities had not shared any theories about what happened or whether there is reason for concern about his safety.
Investigators are continuing to gather information and are urging anyone who may have seen Londergan on or after Monday, or who has any details that could help locate him, to reach out right away. Madison Police can be contacted at 973 593 3000.
This is a developing story, and further updates are expected as police continue their search and share more information about the circumstances surrounding Londergan’s disappearance. Residents in both Madison and Parsippany are being asked to stay alert and report anything unusual, particularly given his connections to both communities.
