HOUSTON (AP) - Condemned inmate Derrick Sonnier received a June 3rd execution date today. He is the third Texas death row prisoner to get an execution date following last week's U.S. Supreme Court ruling upholding the constitutionality of the lethal injection process. The 40-year-old Sonnier was condemned for the 1991 slayings of 27-year-old Melody Flowers and her 2-year-old son Patrick at their apartment in the Houston suburb of Humble. Flowers was stabbed, beaten with a hammer and strangled. Her child was stabbed eight times. Both victims were found floating in a bathtub. Sonnier initially was scheduled to die in February. His execution date was withdrawn by Harris County prosecutors because the Supreme Court's review of lethal injection procedures effectively halted all executions around the country. Last year 26 convicted killers were put to death in Texas, the most of any state. The last execution in the country was in Huntsville on September 25th, the same day the high court agreed to hear an appeal from two Kentucky death row inmates who contended the lethal injection process was unconstitutionally cruel. Their appeal was turned down by the court last week in a 7-2 vote, clearing the way for executions to resume.
