(KRON) -- A South Bay mortuary business and funeral services director are accused of giving a grieving father a bag with his son's brain erroneously placed in it, according to a newly filed lawsuit. The family is suing Lima Family Erickson Memorial Chapel in San Jose, Lima Family Santa Clara Mortua ry, and a licensed funeral director for allegedly mishandling human remains. According to the lawsuit, Alexander Pinon died inside a Santa Clara home in May. His mother signed a contract with Lima to pay more than $10,000 for a "full-service memorial tribute package," including embalming, dressing, casketing, transportation of remains, and a funeral service, the suit states. Pinon's family members decided that, for the funeral, they wanted their deceased loved one to be dressed in different clothing than what he was wearing on the day he died. His father met the funeral director, Annette "Anita" Singh, at the mortuary to retrieve his son's clothing on June 4, attorneys wrote. Singh handed the father a red bag indicating biohazardous material, the suit states, and told him that the bag contained his son's clothing. The father drove directly home, "opened up hiswashing machine, and dumped the contents of the bag straight into the washing machine," attorneys wrote in the lawsuit. The father made a disturbing discovery. "The bag did not contain any clothing, but rather, it only contained human brain matter," attorneys with the law firm Samer Habbas Associates wrote. Pinon's family members had no idea that a coroner had previously performed a cranial autopsy, and part of his brain had been removed. The father "scooped the brain matter out of his washing machine – not aware that it was his son’s brain matter – and puts it back in the red bag," the lawsuit filed in Santa Clara County Superior Court states. He returned the bag and its contents to Singh later that day. The funeral director never offered the grieving father an explanation for how the morbid mix-up happened, nor provided him with his son's clothing, attorneys claim. More suspects arrested after death of OPD Officer Tuan Le Pinon's funeral was held on June 5 and he was buried at Oak Hill Memorial Cemetery. The brain was allegedly left in the bag and hidden for weeks in a courtyard at the funeral home. Attorneys wrote, "The handling of decedent's remains ... has caused plaintiffs extreme emotional distress, trauma, and mental anguish. Discovering one’s own child’s brain matter in a washing machine and then having to scoop it out ... is a horror no family should ever endure. Plaintiffs have suffered shock, grief, nightmares, anxiety, depression, and other lasting psychological injuries ... (and) interfered with their ability to find closure in the grieving process." Funeral homes and licensed funeral directors are professionals entrusted with handling remains in a dignified and respectful manner, attorneys noted. Pinion's family accuses the defendants of negligence, fraud, infliction of emotional distress, and breach of contract. The lawsuit demands a jury trial. ...read more read less
