'Look after Liam' plea
Police have asked a profiling expert for clues
The parents of the 13-month-old boy missing for three days with his grandfather have renewed their appeal for help in finding them.
Mr Evans, a factory worker, said: "There is nothing to be embarrassed about. Don't worry about the press coverage. Just make a phone call if you can't just stop the car and talk to anyone.
"We want you home, both of you."
Sixty police officers are involved in a detailed search of a remote, rural area after a "concentration" of phone calls from the western part of north Wales. There has also been one reported sighting in Germany.
Chief Inspector Bob Cotton said there had been a "tremendous" public feedback after repeated appeals through the media for information.
Profiling expert to give clues
But police say they remain baffled by the disappearance. They have asked a profiling expert to try and give them some clues as to why Mr Evans might have disappeared.
But as time went by it was becoming less likely the grandfather could have been involved in a car accident.
Police are also looking into a call made to a BT operator early on Sunday morning from a public telephone in the Rhondda Valley, south Wales, by a man described as middle-aged and with a Welsh accent - though not a local one.
The caller told the operator: "I have a young child in the car. I have run out of petrol. I have no money." Police have appealed for the caller to come forward.
'Totally out of character'
Liam's parents told a news conference how Mr Evans was devoted to the little boy and his three-year-old sister, Sophia.
Ruth Evans, 28, said: "He wants the children with him all the time. He loves them to bits. They are his life.
"It is just not him - what has gone on over the last two days. It is totally out of character.
"It doesn't make sense. We love him. We want him home, both of them."
To Mr Evans she said: "Please, just look after Liam."
