The 40-year-old suspect, whose name has not been released, is scheduled to make a court appearance Monday afternoon. He is the only suspect in the double homicide.
A sheriff's deputy found the bodies of the two victims - a 20-year-old man and a 66-year-old man - at about 8:30 a.m. Sunday while doing a routine address check on sexual offenders.
Detective Sergeant Jerry Bates said a deputy noticed that the door to the home was open, and found the bodies near what looked like a booby trap, or device, made of hazardous materials.
A bomb squad and hazmat team arrived at the home in the 7700 block of 200th Street East shortly after 10 a.m. to inspect the suspicious device and determined it was an inactive electric fence around an old marijuana grow operation.
Homicide detectives were then able to enter the home Sunday afternoon to investigate the murder scene.
A vehicle associated with the home was later found by Tacoma police officers near South 96th Street and Pacific Avenue South. Four people were initially detained for questioning. One of them was arrested and the other three were released.
