Sioux Falls recorded a higher-than-usual number of homicides in 2014. All six victims were women.

Police say that might be a first in the city because more men are usually killed.

Police say two of the six homicides last year were drug-related, one was considered random and three were the result of domestic violence, including the killing last weekend of 36-year-old Angel Schroeder, a nurse at Sanford Hospital.

Her boyfriend, 39-year-old Timothy Moses, has pleaded not guilty to murder and manslaughter charges.
