The Sarnia Police Service budget is in the red for the first quarter of the year.
As of April 2016, Chief Phil Nelson says they are over by $17,784.
Nelson says a large portion of that is due to overtime.
"Throughout the different parts of the budget we have, we're under in some areas, but what really put a dent into our budget year to date is the fact that we've had two homicides," says Nelson.
"Homicide investigations are very intensive and require a lot of leg work, a lot of work and unfortunately you do get into overtime with these major investigations."
In 2015, Nelson says the overtime pay was over by more than $100,000 mostly due to officers getting injured.
There are 111 officers with the Sarnia Police Service.
