The breakup months ago between a 19-year-old man and his 16-year-old girlfriend, police say, appears to be what allegedly pushed the man to kill his girlfriend’s younger brother last week in Pacific.

Brandon Suhr, an Algona resident, allegedly stabbed to death 13-year-old Walter Denesha (pictured right in a Facebook profile picture), a seventh-grader at Mount Baker Middle School, at the family’s apartment in the Cobble Court complex at 600 Ellingson Road on June 1.

Suhr is in custody at the Norm Maleng Regional Justice Center in Kent on $1 million bail on suspicion of first-degree murder. He also is looking at first-degree kidnapping and residential burglary charges for allegedly forcing the teen girl to leave the apartment with him against her will and for stealing three Japanese swords from the apartment Denesha shared with his sister and mother.

According to probable cause documents obtained from the King County Prosecutor’s office, Suhr got into the apartment by climbing to a second-floor balcony and breaking a window screen.

Once inside, Suhr later confessed to police, he grabbed a knife and stabbed Denesha several times. The King County Medical Examiner’s office on Tuesday confirmed Denesha’s identity and listed the cause of death as multiple stab wounds.

Court documents claim that Denesha’s older sister saw Suhr stab her brother and ran to help him, then struggled with her ex-boyfriend for 10-15 minutes before he choked and subdued her.

The teen girl added that she watched her brother crawl off the bed and into the hallway, where he died.

Suhr then allegedly forced her to take a shower and scrawl a note on the family’s bulletin board that said, “Mom I’m leaving and I’ve killed (Denesha), Don’t look for me and I’ll finish the job.”

In his confession, Suhr told police that they then stuffed Denesha’s body into a closet and he forced the boy’s older sister to leave with him, threatening to kill her if she didn’t. He also allegedly took three swords from the apartment, discarding one on the way to a home in Algona.

At 3:02 a.m. Denesha’s parents placed a 911 call to Pacific police after they returned home to find their children missing, blood in the house and the note.

Police found the boy’s body in the closet.

At 3:24 a.m. Suhr’s mother called police to tell them that her son had showed up at home – in the 300 block of Pacific Avenue in Algona, less than two miles from the crime scene – with the teen girl and told her he had “harmed” Denesha. Suhr’s mother added that the girl told her that “Brandon killed my brother and kidnapped her,” according to court documents.

Police later arrested Suhr after a brief standoff at a home in the 200 block of 2nd Avenue North in Algona. The girl was transported to a local hospital with minor injuries.

Suhr’s Facebook page lists him as a 2011 graduate of Auburn Riverside High School, but hints at a dark side.

Quotations on the page reference the “left-handed path” associated with “black magick,” the occult and Satan worship. In addition, Suhr posted on the website www.vampirefreaks.com as MasterDante666.

A few days before his alleged killing of Denesha, Suhr posted a novelty “License to Kill” certificate on the page, captioning it “Got it to day so don’t —- with me bitches.”

Prior to Suhr’s alleged killing of Denesha, the 16-year-old girl asked her mother about obtaining a no-contact order, according to the prosecutor’s documents.

KOMO News has reported that police investigated Suhr last month for allegedly displaying a weapon, for disorderly conduct and for threats to do harm.

At the crime scene in Pacific last Friday, Byron Kidder, a neighbor, talked to reporters about his buddy.

“He was a really good friend of mine for several years from school,” said Kidder, a sixth-grader at Mount Baker. “We spent several hours at his house playing video games and having Nerf gun wars. He was a really sensible person and a really good percussion player. There is just a lot of talent wasted.”

The White River Valley Lions have set up memorial fund in Denesha’s honor. Donations to help the family with expenses may be made at any Columbia Bank.
