Pullman police are ready to close the investigation into the assault of Washington State University instructor David Warner.

Police Chief Gary Jenkins says he is preparing to turn the case over to the Whitman County prosecuting attorney's office. The prosecutor will decide if any charges are filed.

The 41-year-old Warner was seriously injured while trying to intervene in an argument between an acquaintance and three men outside Adams Mall. He was released from the hospital last week.

Three male suspects have been arrested in connection with the assault, as well as one female suspect for allegedly attempting to cover up the incident. All four turned themselves in to police.

Avista Utilities is taking their services on the road setting up their mobile Energy Resource Team in communities throughout the area. Today, they were in the Spokane Valley with Second Harvest's mobile food bank offering tips and supplies to make homes more energy efficient.

“The biggest goal is to educate people on ways to conserve energy in their homes,” says Ana Matthews, a Consumer Affairs Program Manager with Avista. The Energy Resource Team provides resources and materials to help people who are struggling lower their monthly bills and set them up with resources such as SNAP when they need more help.

Avista workers handed out bags with rope caulk, window insulation kits, fridge coil cleaners and compact florescent light bulbs to help get homes on their way to a lower bill. Matthews says the biggest energy sucker is drafts in the home and they come from places you might not think to look such as your outlets.
