Three men are wanted for the kidnapping and murder of a 57-year-old California man in a case of mistaken identity, according to authorities.
Alberto Alencastro, 25, Alfonso Cresencio Segura Arellano, 20, and Barnabe Antonio Segura Arellano, 22, are facing murder charges filed by the San Joaquin County Sheriff's Office in connection with the death of Avtar Singh.
Incident Overview
According to the San Joaquin County Sheriff's Office, the incident began around 2:30 p.m. on Feb. 17 at a Sikh temple in Tracy, California, located about 60 miles east of San Francisco. The three suspects allegedly forced Avtar Singh, a 57-year-old temple volunteer and resident, into an SUV before driving away from the property.
Investigators later determined through a months-long inquiry that the suspects targeted Singh under the mistaken belief that he had stolen a cargo trailer. Authorities subsequently discovered that the actual thief was in Canada at the time of the kidnapping, making Singh the tragic victim of mistaken identity. Three days after the abduction, the Napa County Sheriff's Office discovered Singh's body near Lake Berryessa, approximately 100 miles north of Tracy.

Victim Information

Community members noted he had recently fathered triplets who were 6 months old at the time of his death. Nearly 3,000 people attended his funeral, and community members established a GoFundMe campaign that raised more than $500,000 to assist his wife and children.
