Police are investigating the deaths of a woman and her two children in East Delhi's Laxmi Nagar. The 25-year-old accused, Yashveer Singh, surrendered and confessed to the killings, citing financial stress, marital discord, and family disputes. He claimed to have mixed a poisonous substance in sweets, but police are skeptical and investigating a potential suicide pact angle. The accused's marriage was reportedly against family wishes due to caste differences, and he had significant unpaid rent and loan issues.
