GARDEN GROVE, CALIFORNIA – The suspect in a Southern California stabbing rampage that left four people dead and two injured pleaded not guilty Friday to murder, attempted murder and other counts. 

Zachary Castaneda was arrested Wednesday by police responding to two hours of slashing and stabbing attacks in Garden Grove and Santa Ana. 

Authorities said Castaneda, 33, was covered in blood when he was taken into custody after walking out of a 7-Eleven store and dropping a knife and a gun that he’d cut from the belt of a security guard he’d just killed. 

The 11 felonies filed against Castaneda also included assault with a deadly weapon to cause great bodily injury, aggravated mayhem, robbery and burglary. 

He was arraigned in his jail cell instead of court. Kimberly Edds, a spokeswoman for the Orange County district attorney, could not immediately say why. 

Castaneda had been kept in restraints when detectives tried to interview him. 

“He remained violent with us through the night,” Garden Grove Police Chief Tom DaRe said. “He never told us why he did this.” 

Information about his defense attorney was not immediately available. 

Neighbors killed

Authorities on Friday said Gerardo Fresnares Beltran, 63, was fatally stabbed in his Garden Grove apartment. His roommate Helmuth Hauprich, 62, was also killed in the attack.  Castaneda was their neighbor. 

Robert Parker, 58, of Orange and Pascual Rioja Lorenzo, 39, of Garden Grove were stabbed separately in Santa Ana. 

Rioja Lorenzo was a construction worker and devout churchgoer from Mexico. 

He had lived in the U.S. for more than a decade but his wife and 16-year-old son remain in Mexico, said Saul Abrego, an official with the United Pentecostal Church La Senda Antigua in Santa Ana. 

Rioja Lorenzo held home Bible study events for the church, and Abrego said he thought he had just come from work and was heading to one such event when he was attacked. 

“It was just a big shock for us,” Abrego said.  

Court records show that Castaneda was a gang member with a criminal history of assault and weapon and drug crimes. 

Castaneda’s criminal history dates to 2004 and includes a prison stint for possession of methamphetamine for sale while armed with an assault rifle. 

Castaneda was convicted in 2009 of spousal abuse and paroled after serving about a year in prison, corrections officials said.  

Police had previously gone to Castaneda’s apartment to deal with a child custody issue, Garden Grove Police Lt. Carl Whitney said. 

The suspect’s mother had been living with him and had once asked police how she could evict her son, Whitney said. 

Wife sought protection

Court records show Castaneda’s wife, Yessica Rodriguez, sought a restraining order last year after she said Castaneda threw a beer can at her 16-year-old daughter. She said she also sought an order against him in 2009 when he broke her arm during a fight. 

Rodriguez filed for divorce earlier this year, court records show, and has custody of two sons. 

Police believe Castaneda killed the two men at the apartment complex where he lived about an hour after burglarizing their unit, then robbed businesses, including a Garden Grove insurance agency where a 54-year-old woman was stabbed. She was hospitalized in critical but stable condition, police said. 

Castaneda is accused of robbing a check-cashing business next door to the insurance agency; a woman there was unharmed. 

Later, a man pumping gas at a Chevron station was attacked without warning and slashed so badly that his nose was nearly severed, police said. He was in stable condition.
