Bruce Macomb, 62, faces a first-degree murder charge for the strangulation of Beba Macomb, 58, early Thursday at their home of 30 years.

Police found the woman's body Thursday afternoon after someone called 911 and asked them to check on the couple at their home at 1620 W. Warren St., just east of South Federal Way.

Bruce Macomb walked out of the home when police arrived and had an injury to his neck, officers say. Police then went inside and found his wife's body.

Police say they have developed undisclosed evidence that Bruce Macomb killed his wife and injured himself. Bruce Macomb was taken to a local hospital for treatment for the neck wound and was arrested after his release early Friday afternoon.

The homicide occurred three days after Matthew Mohler-Kerns, 28, was fatally shot in his car on Franklin Road. No charges have been filed in that case, although Shawn Nathan Fisher - in jail on other charges - is considered a person of interest.

Police have released no information about a possible motive in the Macomb homicide, which investigators believe was premeditated because they recommended prosecutors charge it as a first-degree murder case.

Lynn Hightower, spokeswoman for the Boise Police Department, said they had other possible witnesses in addition to Bruce Macomb, but she declined to release more details.

Bruce Macomb was booked into the Ada County Jail shortly after noon Friday. He won't be able to ask for bond until he makes his first court appearance Monday afternoon.

Public records show Bruce and Beba Macomb lived at the Warren Street home since 1983. A woman who answered the phone at a relative's home declined comment.

Bruce Macomb does not have a felony record in Idaho, according to court records. He pleaded guilty to a DUI charge in 1996 and has had a few traffic infractions since.
