Sierra Vista police have arrested a Fort Huachuca soldier in connection with several felony counts of sexual conduct with a minor, authorities said.

Alexander E. Smith, 27, was arrested Friday and booked into the Cochise County jail on five counts of sexual conduct with a minor, said Sierra Vista Police Department spokesman, Cpl. Marco Madrid.

The seven-week investigation by Sierra Vista PD and the U.S. Army Criminal Investigation Command began on June 8, when police received an anonymous tip that Smith had a sexual relationship with a 14-year-old girl, Madrid said.

Smith reportedly met the victim at a church in Huachuca City, and it's believed that the relationship went on fore more than a year, during which time they engaged in sexual conduct at least five times, Madrid said.

The reported sexual contact occurred in both Sierra Vista, and on base at Fort Huachuca, Madrid said.
