SAN DIEGO (CNS) - A jiu-jitsu enthusiast from Guam pleaded guilty Tuesday to voluntary manslaughter for stabbing his Navy officer brother to death during a drunken fight in the victim's Mission Valley apartment earlier this year.
Zachary Jay Castro Tenorio, 22, faces a maximum of 12 years in state prison when he is sentenced Aug. 23 by Judge Runston Maino.
In an earlier hearing, Deputy District Attorney Roy Lai said the defendant plunged a 6-inch kitchen knife into the chest of his older brother, 25-year-old Navy Ensign Jonathan "Jake" Tenorio, during the alcohol-fueled struggle on Jan. 27 but did not call for help immediately.
Police and paramedics found Jonathan Tenorio dead in a bloody bedroom sometime after 6:30 a.m.
Zachary Tenorio was arrested on murder charges after being questioned by homicide detectives. Lai did not disclose a motive for the slaying.
Jonathan Tenorio, a native of Guam, graduated from the U.S. Naval Academy in Annapolis, Md., in May 2012 and was assigned to the San Diego-based guided-missile cruiser USS Bunker Hill, Navy public-affairs Lt. Rick Chernitzer said.
The brothers' father, Joe Tenorio, told Pacific News Center in Guam that Zachary Tenorio had traveled to San Diego to compete in a weekend jiu-jitsu tournament.
Last summer, the older brother married Christine Santos, an assistant attorney general in Guam and stepdaughter of Frank Blas Jr., a former senator in the U.S. island territory, the father told PNC.
