PEORIA (WEEK) - Trends show violence increases when it becomes warmer outside.
Peoria Police say they can't predict crime, but officers know it's bound to rise as winter turns to spring.
This past weekend, temperatures returned to the 50s, and two people were shot.
To stay ahead, police add more shifts and try to save the department's overtime budget for late spring and summer, when crimes peak and temperatures turn hot.
"That's the goal of everything we do is to reduce that violence," said Peoria Police Captain Brad Dixon.
"The people we know that are pushing that violence, we're following up investigations that we're hoping lead to resolution to those."
So far this year, there have been five homicides in Peoria. Police said they've solved four of those cases. Last year at this time, Peoria had one homicide.
