Toulouse gunman Mohamed Merah may be dead, but French authorities are eying complicity charges for his brother, Abdelkader, reports Sky News. "Police inquiries have produced grave and matching pointers that suggest his (Abdelkader's) participation as accomplice in crimes relating to a terrorist enterprise is plausible," says a statement from the Paris prosecutor's office. The elder Merah, 29, has been in custody since Wednesday, and will be detained indefinitely as charges are weighed, notes the BBC. Abdelkader Merah's companion, variously described as his wife or girlfriend, had also been held since Wednesday, but was released earlier today. (More Abdelkader Merah stories.)
