Rika knew (or at least strongly suspected) Rena was hiding in the junkyard, so she followed the police there and then made a fake call saying she was spotted somewhere else. The problem with that theory is that if she was calling as some anonymous tipster, well, I forget...was the information that the cops were looking for Rena even released to the public? Because that might be suspicious. Maybe if she said she was Rika Furude she'd be expected to know what was going on? But would they expect her to rat out her friend Rena? Even if she's got a high status in the village and is part of the 3 great families, you'd think they might think twice about a young girl so easily selling out her friend, but I'm not sure. Either way I think somehow, if it wasn't Keiichi and co. as a whole, it could have easily been Rika. But most likely it was a false report by the Sonozaki's because in spite of Rena's delusions they were really trying to protect her, right?

Rika was at the dump when they got the report, so it couldn't have been her.
