MISSING man Darrell Simon's family have pleaded with the public to help find him.
Police have been baffled by the disappearance of the 44-year-old Plainland man who has not been seen for two weeks since he disappeared while out for a regular Sunday cycle in the Lockyer Valley.
Speaking at a media conference in Plainland this morning, Darrell's partner Sharon Rowland described their last moments together that morning saying his disappearance was out of character.
"He got up, got dressed, he was going for a bike ride, he gave me a kiss and said I'll see you later," Ms Rowland said.
"It was just like a normal bike ride he does every other morning."
When Darrell didn't return Sharon thought he may have gone to a farm he owns near Laidley so she didn't immediately think that anything was wrong.
"When he goes to the farm he normally takes his keys and I didn't realise until Friday the keys were still at home," she said.
It wasn't until later in the week when Sharon went to the farm and saw the unopened mail that she realised Darrell was missing.
"Darrell, if you are out there somewhere, please let someone know," she said.
"Your family and friends are very concerned and very worried about you."
Darrell's distraught sister Laura Larang-Simon appealed for anyone who was driving in the area that morning to come forward with information.
"If you went past a cyclist when you were driving or saw one go past your house, please report it to the police," Ms Larang-Simon said.
Darling Downs district officer Inspector Mike Curtin appealed for assistance from the broader community in what he said was a very traumatic time for the family.
Insp Curtin said Darrell was last seen around 7 to 8am before he went out riding in the Laidley Plainland area on his black-and-green coloured Ridgeback mountain bike.
"He was seen at an address in Plainland that morning and that was the last time Darrell spoke to anyone - from there we've had no trace of him," Insp Curtin said.
"We've had extensive enquiries in relation to this matter, we've had the police helicopter, we've conducted a number of searches involving SES staff.
"We've also investigated bank accounts, CCTV in the Gatton and Laidley area, and unfortunately at this point in time all our enquiries are exhausted and we haven't located Darrell."
Insp Curtin said Darrell had a mobile phone with him, which last recorded a ping from the Plainland tower around 8am that morning and hasn't been used since.
Police describe Darrell as a 44 year old man who is 183cm high, Caucasian, dark brown hair and brown eyes.
He was last seen wearing a grey t-shirt and black bicycle shorts.
