Those who lost babies say dairy executives won't pay heavily enough for the crimes Parents of babies who were made sick by tainted infant formula were furious yesterday at the 'light sentences' given to Sanlu dairy executives by a Hebei court, which they were barred from going near. Parents from Henan , Guizhou , Gansu and Beijing arrived in the Hebei provincial capital of Shijiazhuang early yesterday morning to try to enter the Intermediate People's Court to hear the verdict, but were denied seats. Roads were blocked, and parents and unregistered journalists were banned from going near the courthouse. The court ordered former Sanlu chairwoman Tian Wenhua to serve a life sentence, the maximum penalty allowed on the charge of 'manufacturing and selling substandard goods'. Three other high-ranking executives will spend five to 15 years behind bars for their roles. Sanlu Group was among 22 dairy companies that sold milk products tainted with melamine, an industrial chemical added to food to boost milk's nitrogen content, allowing it to pass testing for protein levels. Raising a sheet of paper that read 'Give me back my child' and 'Punish all those responsible' outside the police blockade, Zheng Shuzhen , 60, wept upon hearing the sentence and the treatment the parents received. 'She [Tian] killed my granddaughter and made so many babies in China ill. She deserves the death sentence. If my granddaughter died, she should not live,' Ms Zheng said. Ms Zheng's one-year-old granddaughter, who drank Sanlu baby formula from birth, was diagnosed with stones in both kidneys and died in June. Doctors in Zhengzhou told her after the scandal was exposed in September that the formula was to blame. She said she was also angry that parents were denied the right to watch a supposedly open trial, and were barred from getting within a block of the courthouse. Zhao Lianhai , 36, the father of an ill three-year-old boy in Beijing, who gave up his full-time job to campaign for redress, was dismayed and said he saw no justice. 'Tian Wenhua should have been charged with 'endangering public safety with dangerous means' as many legal experts argued, but she was charged instead with the lighter 'manufacturing and selling substandard goods', which excluded the death sentence,' Mr Zhao said. 'I have been against the death penalty, but in this case she deserves it.' Sanlu and the 21 other dairies implicated in the crisis offered 200,000 yuan (HK$227,000) compensation for the death of a child, 30,000 yuan for children suffering from serious illnesses like kidney stones and acute kidney failure, and 2,000 yuan for less severe cases. Last week a Gansu couple who lost their son because of contaminated milk became the first to accept compensation, surrendering their right to sue over their child's death. But other parents have rejected the offer as too low and demanded life-long health care for the sick babies. The scandal has been widely covered by foreign media since it broke last September. Hao Erlong , a 30-year-old taxi driver, said that even though Sanlu was important to the local economy, most people he talked to thought the group had committed unforgivable crimes and nothing short of the death penalty would be suitable punishment for the worst offenders.
