DALLAS -- An attorney for the Iraq War veteran accused of killing a former Navy SEAL sniper and his friend at a Glen Rose shooting range said Wednesday that he will ask for a court-appointed psychiatrist to examine his client.R. Shay Isham, who was appointed to represent Eddie Ray Routh, said the psychiatrist's exam is necessary to determine whether Routh is competent to stand trial.Routh, 25, has not been charged but is being held on suspicion of capital murder in the deaths of Chris Kyle, 38, and Chad Littlefield, 35, both of Midlothian, on Saturday at the Rough Creek Lodge west of Glen Rose.Isham said he had a 15-minute conversation with Routh on Monday but learned little."It was pretty one-sided," he said. "It was more about process, logistics."Routh's other court-appointed attorney, Warren St. John of Fort Worth, said Routh was released from the Dallas Veterans Affairs hospital against his family's wishes just two days before the shootings."There are just so many mental health issues associated with this case," St. John said.Routh is in the Erath County Jail with bail set at $3 million.Erath County Sheriff Tommy Bryant said Routh is on medication but refused to take it Wednesday. He said he doesn't know what the medication is."His mood apparently changes quite a bit," Bryant said.Members of Routh's family have told authorities that he was a troubled vet who had been hospitalized for mental problems, according to records and 911 recordings.Routh's sister told authorities that her brother had come to her Midlothian home on Saturday night and admitted killing Kyle and Littlefield, saying that he was "going to get their souls before they took his," according to information in a search warrant affidavit prepared by the Texas Rangers.
