Ontario sex offender accused of raping Highland senior during home invasion

1231_NWS_IDB-L-ATTACK

Detectives Wednesday arrested a convicted sex offender from Ontario on suspicion of the rape of a Highland senior citizen during a home invasion earlier this month, authorities said.
Antawon Riley Stubblefield, 27, is accused of rape, oral copulation by force, false imprisonment and home-invasion robbery in connection with the attack and robbery, which took place on the afternoon of Dec. 8 at the victim’s home in the 7800 block of Lankershim Avenue, Highland police officials said in a written statement.
“Investigation revealed that an unknown suspect forced entry into the 67-year-old victim’s residence and attacked her as she watched television,” according to the statement. “The suspect then held the victim against her will inside of her home; during which he sexually assaulted her several times over a four-hour period.”
The attacker stole cash and other items from the victim before fleeing her home. The woman was hospitalized for treatment, and her attacker was not found.
Detectives were notified by crime lab officials Tuesday that DNA collected at the crime scene has been matched to Stubblefield, officials said. Stubblefield was already on felony probation and a registered sex offender for a previous assault conviction.
Officials obtained a warrant for Stubblefield’s arrest, and took him into custody Wednesday when he reported to his probation officer, police said.
Authorities added that detectives are seeking any additional people who may have been victimized by Stubblefield.
According to San Bernardino Superior Court records, Stubblefield was awaiting sentencing in his previous case at the time of the Highland attack. He was released from custody Nov. 16 after being granted a waiver allowing him to be free from custody pending formal sentencing.
The Highland home-invasion took place less than a month later.
Stubblefield had pleaded “no contest” to a count of assault likely to produce great bodily injury and engaging in prostitution stemming from a Sept. 1 arrest, records show. An additional count of attempted forcible rape was dismissed by the court.
He was sentenced under AB 109 guidelines, which state officials say is intended for “non-violent, non-serious and non-sexual” offenders.
He received a sentence of 150 days in jail, with credit for time already served and good behavior. He was also sentenced to three years of Post-Release Community Supervision and ordered to register as a sex offender for life.
He was formally placed on felony probation at a hearing Tuesday, the same day his DNA was linked to the Highland crime scene.
Stubblefield was being held without bail Wednesday at the West Valley Detention Center pending his initial court appearance, officials said.

0822_NWS_SGT-L-RAPEARREST2crop

EL MONTE >> Police arrested an alleged rapist also sought in connection with the murder of a Fresno County woman Friday after a neighborhood search that lasted about four hours, officials said.
Kaleo Kealoha Schreiner, 21, of Tracy, was ultimately arrested for rape, possession of a loaded gun in public and resisting police, El Monte police Sgt. Richard Luna said in a written statement.
Police first received a report a woman had been raped about 5:10 a.m. in a residential neighborhood in the 4100 block of Tyler Avenue, the sergeant said. The attacker was reported to still be at the scene of the crime and armed with a handgun.
Police spotted a man matching the suspect description running in the 3800 block of Tyler Avenue and set up a search perimeter, Luna said. West Covina and Arcadia police joined in the search, along with a Los Angeles County Sheriff’s Department helicopter.
A police K-9 found Schreiner hiding behind a garage in the 3800 block of Esmeralda Ave., officials said.
“The canine bit Schreiner, who resisted the canine and ignored officer’s commands to comply with the arrest,” Luna said. “A bean bag was deployed on Schreiner, who then complied, and was taken into custody.”
Police found a loaded handgun in the area where Schreiner had been hiding, Luna added.
Schreiner has been sought by the Fresno County Sheriff’s Office for more than two weeks as a suspect in the slaying of Megan Troen, 20, of Tracy, whose body was discovered July 30 in the California Aqueduct, near W. Nees Avenue and the 5 Freeway in the Firebaugh area, Fresno County sheriff’s officials said in a written statement.
Troen had left her home with Schreiner, an acquaintance of several years, July 20 and was never seen again. Investigators said Troen had a diminished mental capacity.
In the days and weeks that followed, Fresno sheriff’s homicide detectives identified Schreiner as a suspect in the slaying and issued a warrant for his arrent.
Officials took Schreiner suspect to a hospital for treatment prior to booking him into jail, he said.

Three additional suspects charged with 2002 kidnapping, slaying of Montebello teen

AR-150309859

MONTEBELLO >> Prosecutors have charged three additional suspects in connection with the alleged rape and murder of a 15-year-old Montebello girl on her way to school more than 12 years ago.
The three men join a woman who is already awaiting trial on charges related to the Oct., 2002, slaying of Brenda Sierra, Los Angeles County District Attorney’s officials said in a written statement.
Eddie Chavira, 20, Daniel Cervantes, 35 and George Barraza, 35, were added to a felony complaint alleging murder and other charges already filed against Rosemary Chavira, 28, district attorney’s office spokeswoman Jane Robison said.
Rosemary Chavira, Cervantes and Barraza are each charged with murder, conspiracy to dissuade a witness and forcible rape, along with the special circumstance of murder during the commission of a kidnapping to benefit a street gang, court documents show.
Eddie Chavira faces charges of murder and conspiracy to intimidate a witness.
Sierra was on her way to Schurr High School in Montbello when she was kidnapped on Oct. 18, 2002.
“She was raped and killed,” according to the district attorney’s office statement. “Her body was found the following day in the Crestline area of the San Bernardino Mountains. The cause of death was determined to be blunt force trauma to the head.
Sierra had no gang ties, investigators said. But she may have been killed so send a message to the community to keep quiet about gang violence.
In the days before Sierra’s kidnapping and slaying, “Eddie Chavira was in custody for a shooting witnessed by victim Brenda Sierra’s relative,” the district attorney’s office statement said. “Chavira told a fellow Lott gang member that he was going to have other Lott gang members take care of a witness. About the same time, he contacted his (then-)15-year-old sister, Rosemary Chavira, to assist in getting other gang members to take care of witnesses.”
Eddie Chavira and Daniel Cervantes are each serving prison time for previous convictions, authorities said. Investigators arrested Rosemary Chavira in February. Barraza remains a fugitive.
Rosemary Chavira has pleaded not guilty to her charges and is due back in Los Angeles Superior Court Tuesday for a preliminary hearing.
Arraignment dates were yet to be scheduled for Eddie Chavira and Cervantes.
Because Rosemary Chavira was herself a teen at the time of the killing, she faces a maximum penally of life in prison without the possibility of parole if convicted as charges, prosecutors said. Eddie Chavira faces up to 25 years to life in prison if convicted.
Cervantes and Barraza’s alleged crimes make them eligible for the death penalty under California law, however authorities have not yet determined whether to seek capital punishment in the case.

0412_NWS_WDN-L-DIOFRON1

NORWALK >> A man accused of sexually assaulting and fatally stabbing his disabled neighbor in Norwalk before fleeing to Guatemala returned to the U.S. Friday to face charges, authorities said.
Luis Fernando Diofron, also known as Luis Fernando Diofron Lemus, 22, was extradited back to Los Angeles County via LAX following his Dec. 4 arrest in San Miguel, Escuinta, Guatemala, FBI spokeswoman Laura Eimiller said.
Diofron is suspected in the brutal stabbing death of 50-year-old Denise Battey Aug. 10, 2012, at her home in the 11900 block of Allard Street, according to Los Angeles County sheriff’s officials
He’s charged with murder, with the special circumstances of rape and burglary, FBI spokeswoman Laura Eimiller said.
After Diofron allegedly fled the country, federal authorities also charged the suspect with unlawful flight to avoid prosecution. But the federal case is expected to be dismissed as the Los Angeles County District Attorney’s Office prosecutes the murder case.
Diofron, who was living near Battey while in the U.S. on a work visa, attacked and sexually assaulted Battery as she watered her garden, according to sheriff’s officials and her twin sister, Annese Battey.
He then dragged her inside her home and stabbed her to death, authorities allege.

Man convicted of 1981 rape, killing of Whittier woman

Joseph Allen Thornton

WHITTIER >> A man arrested more than 30 years after the 1981 rape and killing of a woman inside her Whittier home pleaded “no contest” to four felony charges Tuesday, on what would have been his victim’s 55th birthday, authorities said.
Joseph Allen Thornton, 53, immediately received a sentence of 24 years to life in state prison after entering his pleas in Norwalk Superior Court, Los Angeles County District Attorney’s office spokeswoman Sarah Ardalani said.
Initially charged with murder, Thornton pleaded “no contest” to voluntary manslaughter, rape, sodomy by force and digital penetration by force, district attorney’s officials said.
For more than 30 years, Thornton had gotten away with the June 27, 1981, slaying of 21-year-old Blanca Negrete in her home in the 7900 block of Washington Avenue.
“At the time of the slaying, detectives had exhausted all leads and the case eventually went cold,” Ardalani said in a written statement.
Blanca Stella NegreteBut Whittier Police Department investigators reopened the cold case in 2010, and identified Thornton as a suspect in the crime in January of 2011 via previously unusable DNA evidence, police officials said at the time.
DNA evidence had been collected by investigators after the slaying occurred, however the technology of the time did not allow investigators to match it to a suspect, police said in a written statement. Thornton’s DNA had been entered into a law enforcement database as the result of a domestic violence conviction, Whittier police Lt. Kent Miller said at the time.
Once identified as a suspect, police turned their attention to locating and capturing Thornton, Miller said.
The trail led them as far away as Topeka, Kansas, where Thornton had stayed for many years after the killing, he said. Detectives ultimately tracked him down and arrested him in April, 2012, at his home in Auburn.
Negrete worked at what eventually became PIH Health Hospital at the time of her slaying, police said. What, if any, relationship that existed between her and her killer was unclear.
The conviction occurred on what would have been Negrete’s 55th birthday, Whittier police Officer John Scoggins said.
In addition to his prison sentence, Norwalk Superior Court Judge Yvonne T. Sanchez ordered Thornton to register as a sex offender for the rest of his life, Ardalani said.
