To say it’s been a difficult time for the family would be an understatement.
“He lived on a disability pension, he suffered from depression… we just want him to come home,” she said.
“He is a gentle giant, he looks like a bikie-kind of bloke, but he’s not, he’d curl up if you tried to pick on him.”
Mrs Sullivan was distressed to find a WA Police missing person report stated her son had no fixed address and was living in his car.
She wanted to correct this description, asserting he lived with her and his father at their Burns Beach home, but chose to sleep in his car parked outside.
“Mark slept in his car for the last seven years, but he had a home here,” she said.
“At night he slept in his car, but the next morning he was back in the house… this is his home address.”
The police release also said his mother last saw him at Currambine train station about noon on Saturday, October 31, which Mrs Sullivan said was incorrect.
She contacted the Times to put the story straight, in the hope it might better assist in finding him.
She said the last time she saw Mr Sullivan was at their Grand Ocean Entrance home about 8.30pm on October 31.
The missing man’s uncle and cousin were the last people to see him about 9.30pm that night when they said goodbye to him in his car after visiting the family.
Mrs Sullivan said her son’s car was locked and he was gone the next morning, but she was not concerned because he told her he had planned to go fishing with a friend.
She did not see him on Sunday night and began to worry when a Joondalup Health Campus representative rang her on Monday to say he had not picked up his scheduled medication.
More than 2½ months later, the Sullivans remain in limbo as to his whereabouts and safety.
“His car is still parked outside our house, the police have searched his car, found a few phone numbers, they’ve all come back negative,” Mrs Sullivan said.
“Now I’m in the process of having to sell the car because it can’t stay parked behind our garage and the shire (City of Joondalup) wants the car moved, which is fine.”
Police said the investigation was continuing. Anyone with information can call Crime Stoppers on 1800 333 000.
