HOUSTON (AP) - The U.S. Supreme Court has refused to hear the cases of two Texas death row inmates.
Justices rejected a review for Derrick Sonnier, a suburban Houston man convicted of beating, stabbing and strangling a woman and her toddler in 1991.
The victims were Melody Flowers and her two-year-old son, Patrick.
Prosecutors say Sonnier lived in the same Humble apartment complex as Flowers and had bothered her several times, including two break-ins at her home.
Elroy Chester was condemned for fatally shooting a Port Arthur fireman nine years ago.
Chester confessed to the slayings of at least four other people during a six-month crime spree.
He pleaded guilty to killing Willie Ryman III, who was trying to keep Chester from raping his two nieces at their Port Arthur home during a burglary.
The Supreme Court in 2002 barred the execution of mentally retarded people. A federal judge that year ruled Chester's trial court never determined whether he was retarded.
A federal court in 2003 refused to rule on Chester's appeal until all state appeals were exhausted.
The Texas Court of Criminal Appeals in February had refused to overturn a lower court ruling that said Chester is not mentally retarded.
