The Crescenta Valley sheriff's station, which patrols La Canada Flintridge and some nearby Los Angeles County territory, reported a 15.8% drop in major crimes during the three-month period.
Deputy Jack Barnes said the most dramatic change was in residential burglaries, which were down 50%--from 92 to 46 incidents--from the January-March period of 1984.
Barnes attributed much of the decrease to the station's crime impact program, which uses a team of deputies who gather data on when burglaries occur, how the burglars got in the home and what parts of the city are being hit hardest.
Deputies use the information to stake out neighborhoods where burglaries are frequent.
The program has helped crack down on commercial and car burglaries. Commercial burglaries dropped from 58 in the first quarter of 1984 to 31 this year; car burglaries fell from 31 to 24, Barnes said.
