A 49-year-old man was sentenced today to 50 years to life in state prison for killing a former coworker and then hiding his body by encasing it concrete under a Santa Fe Springs business, the Los Angeles County District Attorney's Office announced.

Deputy District Attorney Steven Schreiner said Juan Alberto Galvez was found guilty on Oct. 23 of one count of first-degree murder.

The jury also found true the allegation that Galvez used a shotgun to commit the murder and foundhim guilty of misdemeanor possession of methamphetamine in case VA128108.

On Dec. 23, 2012, Galvez shot Guillermo Díaz, 38, at a skylight manufacturing business where both men previously worked together, according to court testimony. Galvez had grown resentful toward Díaz after being fired from the skylight business, according to the evidence presented at trial.

In an effort to hide the victim's body, Galvez encased it in cement and buried it under a makeshiftshower he constructed at an auto repair business where he worked within the same industrial park area, the prosecutor said.

The Whittier Police Department investigated the case.
