Seghelmeble asked the judge, not a jury, to sentence him. The Dallas Morning News reports Judge Gracie Lewis considered the man's diagnosis of paranoid schizophrenic, but also noted the "extreme nature" of the slaying.
Relatives say Seghelmeble was on disability for mental problems at the time of the killing.
The judge last week ruled Seghelmeble was competent, after questions about his ability to assist his attorney led to a mistrial days earlier.
