Missing Adrian Lynch: House-to-house search begins
Police searching for a man missing since Saturday morning have started house-to-house inquiries.
Emergency services have been searching for Adrian Lynch, 20, who was last seen at 02:00 GMT on Saturday in the Carrefour Selous area.
States of Jersey Police said officers are likely to revisit residents they have spoken to before.
More than 4,000 people have signed up to a Facebook group offering to support the search.
Mr Lynch's parents, Sharon and Danny Lynch, said: "We have seen first hand the work that is going into the search and we are tremendously grateful and overwhelmed."
Police and other emergency groups scaled down a search overnight due to poor light and resumed in full on Thursday morning, when the Channel Islands Air Search plane made checks over Trinity, St Lawrence, St Mary and St John.
A crew member said: "We searched each of these thoroughly but despite having excellent visibility throughout the flight, no sightings of Adrian were made."
Police said two further potential sightings of Mr Lynch on Saturday morning were reported on Wednesday.
A force statement: "We are also asking islanders to keep a lookout for Adrian's Yale door key and a key to a Ford Fiesta, which his family now believe are not at the home address.
"Adrian was also wearing a gold signet ring."
