Police looking for a missing Cardiff mother have searched the drains in streets near her home.
Lorraine Ridout, 57, left her house in Gabalfa to visit a friend at 7pm on January 31 and has not been seen since.
Despite land searches and police divers scouring the river, no clues about what happened have turned up.
“On June 2 they were looking under manhole covers in Gabalfa,” Lorraine’s daughter Christine said.
She spotted a police team outside her home on Aberporth Road, Gabalfa.
“I opened my curtains on June 2 and I saw a team of four and I went over and asked them what they were doing.
“Then they went to Heol Amlwch,” Christine said.
The police told her they had no evidence Lorraine was in the drainage system but they had to look as “a line of inquiry.”
Christine said she had been convinced her mum had fallen in the River Taff.
Before she went missing mum-of-three Lorraine lived with her husband Steven, also 57.
Christine was “anxious that they are never going to find her.”
“It’s been over 18 weeks now,” Christine said.
“It is not getting easier, it is getting worse.
Lorraine’s family joined the search to find her
“It is really hard to get motivated. You just plod along because you have to.
“I have been in work, but the days I am at home, that is my time. So if I am upset I can be.
“I work in the care industry and it would not be professional in work.”
Lorraine, who has mental health issues, has been missing her daily medication since she disappeared.
“We are just a broken family now,” Christine said.
A South Wales Police spokeswoman said: “We have been searching and ruling out the possibility of the drainage system.”
She added: “We have done a thorough search of the area, especially difficult to access areas.”
