The number of adults charged with felony crimes in Dakota County -- from violent assaults to burglaries -- fell by 12 percent last year compared to 2008, according to statistics released Tuesday.
Overall, the number of assaults, terroristic threats and other violent felony cases dropped by 17 percent, from 646 to 539. But felony sex cases, murder and manslaughter charges inched up.
The numbers refer strictly to adult prosecutions, not crimes reported to law enforcement. Those figures emerge much later.
Three of the six victims slain last year were children 10 years old or younger who were killed by family members, Dakota County Attorney James Backstrom said.
They included a beaten Northfield toddler who suffered a brain injury and broken back that went untreated for days before he died; a 10-year-old South St. Paul boy poisoned by his mother, who also tried to kill another child and herself; and a Lakeville grandmother who mixed prescription drugs and alcohol and fell asleep atop her infant grandson, smothering him.
Still, deadly violence remains rare in the county.
"Dakota County has averaged four homicides per year, which is remarkably low for a jurisdiction of almost 400,000 persons," Backstrom noted.
Only Farmington and Hastings showed increases in felony crimes charged. Farmington had 41 felonies prosecuted in 2009, compared to 26 in 2008. Hastings saw an increase of four cases, up to 86.
