The father of murdered 12-year-old Mercedez Layne broke down in tears today after learning the results of an autopsy which confirmed that his daughter died from blunt force trauma to the head.Ronald Cabrera, speaking following the examination, said no punishment could ever undo the pain his family is experiencing.The autopsy was conducted on the body of the Erin RC Primary School student, whose partially clothed body was discovered near an oil well along Carapal Road, Erin, on Sunday morning, hours after she had been reported missing.Fighting back tears, Cabrera said he was told the injuries to his daughter's head caused the bleeding from her ears that had shocked relatives when her body was found."What am I supposed to do?" he asked."Could anything bring back my daughter? You could get a million years. Could you bring back my daughter? And if I get a million years and I put my hands on him, would that bring back my daughter? Why taxpayers have to be paying for people who do certain crimes?"A 24-year-old man from Palo Seco remains in police custody as investigators continue enquiries into the child's death.The killing has horrified the nation and sparked renewed calls for stronger measures to protect children.Mercedez's body was discovered shortly after 6.40 a.m. on Sunday by a worker employed with Trinity Exploration and Production Services, who was on his way to conduct maintenance work at Well ER-46 along Carapal Road.Police said the worker found the child lying motionless on the ground and immediately reported the matter to the Erin Police Station.Responding officers found the body approximately 500 feet along a dirt track leading to the oil well. The child was lying face down and clad only in a green T-shirt. She was nude from the waist down.Crime scene investigators recovered several items from the area, including clothing believed to belong to the child, a broken bottle, a slipper, food items and other pieces of evidence.Investigators later learned that Mercedez had been reported missing around 4 p.m. on Saturday by her grandfather, Morriso Gastoigne.He told police he last saw the child around 11.30 a.m. when she entered a pink-coloured station wagon driven by a man unknown to him. The vehicle was reportedly headed towards her home along Los Iros Beach Road, but she never arrived.Member of Parliament for La Brea Clyde Elder, who visited both the crime scene and the family's home on Sunday, described the murder as a devastating blow to the close-knit community."This has been a shocking, heart-wrenching, gruesome, vexatious act committed," Elder said."The community of Los Iros, Carapal, Erin, is close-knit, and I think what has happened has left us all as a community in a state of disbelief. Right now people are just hoping for justice."Opposition Leader Pennelope Beckles also expressed condolences to the family and called for urgent action to strengthen child protection systems."The apparent rise in incidents involving missing and abducted children in recent months warrants urgent and coordinated action by the State to strengthen child protection measures, improve public safety systems, and enhance community awareness," Beckles said.
