When Adams began corresponding online with a fan, Ava, in 2013, she was a 14-year-old bass player already forging a career.
But their correspondence about music turned into graphic texting. Eventually, Ava said, they conducted video calls on Skype, where Adams exposed himself during phone sex.
The Times has reviewed extensive communication between the two, including 3,217 text messages they exchanged over a nine-month period when Ava was 15 and 16.
In the texts, Adams questioned Ava repeatedly about her age, and sometimes she said she was older than she was. Though he did not seem convinced, their sexual conversations continued. "i would get in trouble if someone knew we talked like this," Adams wrote to her in November 2014.
