A welfare check on two people who had not been seen all day led Davis officers to two bodies.
Davis Police were contacted Sunday evening with a request to check on the home along Cowell Boulevard, near I-80 and Mace Boulevard.
Officers found two people dead, and signs that someone had forced their way inside.
Investigators believe both people were killed, however they have not determined a motive or released any suspect information at this time.
Davis Police told FOX40 homicides are rare in their city, there were none in 2012 and two in 2011.
Anyone with information about this incident can call (530) 747-5400.
