What happened

Soil testing at a property linked to the man convicted in the murder of California college student Kristin Smart, who disappeared in 1996, turned up evidence of human remains, a state sheriff announced on Friday.

Why it matters

“We can’t call it Kristin, but there’s evidence to support human remains – there at one time,” the San Luis Obispo county sheriff, Ian Parkinson, said at a news conference.

Common ground

Smart went missing from California Polytechnic State University in May 1996 after returning from an off-campus party.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
