U-T San Diego reports that detectives found a phone at the Chula Vista crime scene, where a laptop, cash and watches were stolen.
On the phone was a photo the suspect had apparently snapped of himself.
Residents recognized the man in the photo, and police arrested 26-year-old Adam Howe on Tuesday.
A search of his belongings uncovered property believed to be stolen from the Hilltop Tabernacle Church.
Further investigation led to the arrest of two other people.
Police say they've now linked Howe to thefts at a nearby mobile home park after residents recognized his picture in media reports.
A phone number listed in Howe's name rang without an answer Thursday.
