An important principle of criminal investigation, as articulated by detectives in fiction, is that wrongdoers frequently return to the scene of their crimes. Believers in that theory might say it could apply to the arrest made in the rape of a jogger last week in Montgomery County.

About 4:15 p.m. Monday, the jogger, a woman in her 20s, was running on a trail in the Northwest Branch in the Silver Spring area. She was approached by a man with a knife who forced her off the trail near Oakview Drive, raped her and fled, Montgomery County police said.

On Friday, authorities said, investigators from the Maryland-National Capital Park Police, who were investigating the case together with county police, went back to the vicinity of the crime and searched for additional evidence. In an area off the marked trail, county police said, park police detectives spotted a backpack.

According to the description that the victim had given, the assailant had a similar backpack, county police said.

Farther on, authorities said, the park police detectives spotted a man who also appeared to fit the description given by the assailant. In addition, police said, the man wore a beaded necklace like one described by the victim.

The man was detained by the park police and taken to county police headquarters, where he was questioned, authorities said.

After the questioning, Montgomery County police said, Joaquin A. Oreliana Torres, 24, of Hughes Road in Hyattsville, was charged with one count of first-degree rape and one count of armed robbery.

The chief of the Montgomery division of the park police said the arrest helped “to maintain the safe environment for everyone who uses the Montgomery County park system.” He praised the investigators and the coordination between county and park police.
