(USA TODAY Network Louisiana) – Louisiana State Police investigations are ongoing in 10 crashes resulting in 15 deaths.

The accidents happened over the weekend and early Monday morning, according to a release from the agency.

Alcohol impairment, excessive speed and lack of seat belt use were factors in several of the crashes.

“As Troopers, the most difficult part of our job is informing someone that their loved one is not coming home,” Louisiana State Police Superintendent Kevin Reeves said. “Fifteen deaths in a weekend is beyond tragic, but even one death is too many especially when preventable. By simply taking some extra precautions when you travel, you can greatly increase the chance that you will return home safely each and every trip.”
