Remains of Southern California woman murdered in 2023 found in shallow grave
A 44-year-old man from San Bernardino County is being extradited from an Arizona jail back to Southern California where he's accused of a 2023 murder of a 43-year-old woman, officials announced.
Investigators with the San Bernardino County Sheriff's Department's Colorado River Station received reports in Feb. 2024 that the victim, Tyna Castillo, a resident of Needles, had not been seen or heard from since Dec. 2023 and opened a missing persons case, according to an SBSD news release.
Detectives received information during the investigation that Castillo was possibly murdered on a residential property in Needles.
'Detectives contacted witnesses and people of interest in Castillo's disappearance and received poor cooperation,' officials said. 'The case went cold, and Castillo was not located.'
SBSD's Cold Case Homicide Team took over the investigation in Sept. 2024 and learned the possible location of the 43-year-old woman's remains.
After eight failed attempts to locate her remains, detectives, with the help of search and rescue teams, cadaver dogs and 100 volunteers, found Castillo buried in a shallow grave in an open desert area along the Colorado River in Needles.
Further investigation led to Needles resident Jared Winer, who detectives claim killed Castillo by shooting her.

Authorities did not provide any details on the relationship between Castillo and Winer, nor did they provide a possible motive for homicide.
Police in Bullhead City, Arizona, approximately 23 miles from Needles, arrested Winer and booked him at the Mohave County Jail on unrelated charges. SBSD detectives learned of the arrest and obtained a murder warrant for the 44-year-old.
He is expected to be extradited back to California on the murder charge after the disposition of his outstanding charges in Arizona, officials said, though they did not provide an exact date.
Anyone with information about this case is asked to contact SBSD Det. Justin Carty or Sgt. Justin Giles at the Specialized Investigations Division at 909-890-4904. Those wishing to remain anonymous can call the WeTip Hotline at 800-78CRIME or leave tips online at www.wetip.com.

42 arrested in Inland Empire smash-and-grab crackdown
The San Bernardino County Sheriff's Department announced several dozen arrests in its continuing crackdown on retail theft crews. Between May 17 and 30, SBSD personnel and representatives from local, state and federal agencies arrested 42 people across the county, the SBSD said in a news release. Of those 42 arrests, 10 were for felony charges and 32 were for misdemeanors. Additionally, more than $8,100 in property was recovered, authorities said. The arrests are part of Operation Smash & Grab, which targets retail theft, especially in 'the Rancho Cucamonga, Apple Valley, Hesperia, Victorville, and Chino Hills shopping districts,' the release said. These robberies, burglaries, vandalism and other crimes are done by crews of organized thieves who 'terrorize the citizens of San Bernardino County by utilizing intimidation tactics and a mob mentality that creates an unsafe and uncomfortable shopping environment for our residents,' according to the Sheriff's Department. Officials added that Proposition 36, which enacted harsher penalties for shoplifters, applied to five of the arrests. Copyright 2025 Nexstar Media, Inc. All rights reserved.
