Frankston Crime Investigation Unit detectives continue to appeal for public assistance and will today conduct a search for missing Frankston North man Ronan.
The 54-year-old was last seen walking west along Beach Street at 6.12pm, and then walking past Kinetic Stadium on Kars Street about 6.45pm on Tuesday, 28 May.
Earlier in the afternoon, Ronan was seen leaving a medical facility on Hastings Road towards Frankston CBD. He was also seen walking past a chemist on Davey Street about 4.00pm.
Police and family continue to hold concerns for Ronan's welfare as he lives with epilepsy and an acquired brain injury which both require medication. His disappearance is extremely out of character.
Beginning Monday 21 October detectives, along with SES volunteers, a five-day search will begin focusing on the Frankston CBD and residential areas south of Kinetic Stadium.
Officers are also appealing for residents in Frankston South, specifically those residing in and around High Street, Warringa Road, Cliff Street and Foot Street, to check their properties and review any CCTV footage they might have from the 28 May.
Ronan is Caucasian in appearance and approximately 167cm tall with dark shoulder length hair and a grey beard.
He was wearing black tracksuit pants, a faded black hoodie, black runners, and black rimmed glasses.
Detectives have released images and CCTV of Ronan in the hope that someone can provide information on his current whereabouts.
Anyone who sights Ronan is urged to contact Frankston Police Station on (03) 9784 5555.
