Tucson Police have arrested a suspect and are still looking for several others in connection with a sexual assault of a 13-year-old girl in April.

50-year-old David Manuel Samaniego, Jr., was taken into custody at a residence near East 22nd Street on July 31. He was charged on suspicion of sexual conduct with a minor.

The girl was a passenger on Sun Tran’s Route 17 bus on April 1, according to a news release from TPD. Police said an older man approached her and convinced her to go to his home near East Kleindale and North Country Club roads.

The girl ingested an unknown substance, lost consciousness at the residence and eventually regained consciousness to find herself surrounded by the man and other men, the news release said. Police say some of the men had sexually assaulted her during that time, the release said.

The assault was reported to patrol officers the following day.

A second suspect has been identified as 70-year-old David Manuel Samaniego, Sr.

Two more suspects have yet to be identified. Anyone with information on Samaniego, Sr., or the two suspects are asked to call 88-CRIME.
