FAIRFIELD  (AP) — Police said Friday they have arrested a barber in the death of a 13-year-old girl whose naked body was found last week in a Northern California park.

Anthony Lamar Jones, 32, of Fairfield was taken into custody after police had him under round-the-clock surveillance as the main suspect in Genelle Renee Conway-Allen's slaying. During a news conference to announce the arrest, police said they believe Jones, who was identified early in the investigation as a suspect, acted alone in the killing.

They did not say how the girl died, citing an ongoing investigation.

"We have evidence linking Jones to this homicide, and we believe at this time that there are no other suspects named in this case," Fairfield Police Sgt. Rebecca Belk told reporters.

Jones worked at a barber shop less than two miles from his home. Police had the shop blocked off with crime-scene tape Friday afternoon.

The seventh-grade girl was reported missing Jan. 31 by her guardian at a foster home in nearby Suisun City. The teen was last seen at a bus stop after taking a bus from her middle school. A video camera caught an image of her talking on a cellphone wearing a pink Hello Kitty backpack.

A passer-by found the girl's body the next morning in Allan Witt Park.

The teen's foster family said in a statement read by Belk that they were overwhelmed with emotion after learning about the arrest.

"Finally, with tears in our hearts, we can now begin to say goodbye to sweet Genelle," the statement read. "Genelle, we love you so much. We always will. May you find peace forever. We will always, always love you."

A vigil for the teen was scheduled for Friday night.
