The main suspect who kidnapped and killed four members of an Indian-origin Sikh family, including a baby girl, in California has entered a not guilty plea in court, authorities said. The Sikh family of four, 8-month-old Aroohi Dheri, her 27-year-old mother Jasleen Kaur, her 36-year-old father Jasdeep Singh, and her 39-year-old uncle Amandeep Singh were kidnapped at gunpoint and killed allegedly by Jesus Salgado, a former disgruntled employee of their trucking company.

Salgado entered a not guilty plea in court on Thursday, Merced County Chief Deputy District Attorney Matthew Serratto was quoted as saying by CNN. Salgado, who was arrested on October 6, is charged with four counts of first-degree murder with special circumstances for the death of the Indian-origin family. He is also charged with arson and possession of a firearm by a prohibited person.
