"I was just looking to get someone," Ethan said. "He just happened to be a cop."
He contacted authorities last month after he and Davies started messaging one another.
Police said the pair began speaking May 11 on Tinder and that, after the conversation moved to Kik Messenger, Ethan told Davies that he was actually a 16-year-old girl claiming to be 19 to use Tinder. The dating site does not allow minors to create accounts.
"We started texting on there, and it got a lot more explicit," Ethan told KNTV.
Police said Davies acknowledged that “Esther” was 16 years old and that they “chatted about engaging in sexual activity” in subsequent conversations on Snapchat.
In a statement released last week, San Mateo police said Davies was placed on administrative leave in light of the ongoing investigation.
“This alleged conduct, if true, is in no way a reflection of all that we stand for as a department,” San Mateo police Chief Susan Manheimer said Thursday, adding that the alleged incident “is an affront to the tenets of our department and our profession as a whole.”
Authorities continue to investigate.
