San Diego ABC News Affiliate KGTV says police have not released the identity of the suspect, but said the "man" would be arraigned tomorrow (Wednesday, Guam time) in San Diego.
A search on the San Diego Sherrif's Department website of inmate's currently detained lists a Zachary Castro Tenorio, 21. It states he's currently being held without bail for murder in the first degree. The website also states that he was booked and confined around 6:30 pm Sunday, or about 12 hours after Jake Tenorio's body was first reported.
Zachary is the brother of Jake and he was in San Diego for a jujitsu tournament this past weekend.
KGTV reports that San Diego Police have confirmed that a suspect was arrested about 10 hours after the investigation was launched. Police have also confirmed that Jake Tenorio died of a single stab wound.
The brothers' father, Joe Tenorio, told PNC News yesterday that the last communication he had with his son, Jake, was Sunday, Guam time. The elder Tenorio says he sent Jake a text message asking him to tell his brother, "Good luck" in his jiu jitsu tournament. Zach Tenorio is known in the Guam community as a martial artist and multiple sources have confirmed that he was scheduled to compete in a jiu jitsu tournament in San Diego this past weekend.
Jake Tenorio graduated from the U.S. Naval Academy last May and was stationed in San Diego, assigned to the U.S.S. Bunker Hill. He grew up in Mangilao and graduated from George Washington High School in 2004.
His father, Joe, says, Jake is a newlywed and just got married last summer to Christine Santos Tenorio. Santos is the step-daughter of former Sen. Frank Blas, Jr.
Joe Tenorio says Christine Santos Tenorio is an Assistant Attorney General here on Guam and recently returned to the island after visiting her husband for the holidays.
