HOUSTON (AP) - A jury has resumed deliberating in the trial of a man who claims he was insane when he fatally shot six members of his ex-wife's family, including four children, in suburban Houston.

Jurors in the capital murder trial of Ronald Lee Haskell deliberated for about 3½ hours on Wednesday. They returned to deliberations on Thursday morning.

The jury has been sequestered during deliberations.

Haskell's lawyers told jurors he committed the killings but should be found not guilty by reason of insanity because his judgment was impaired by severe mental illness.

Prosecutors say the 2014 killings were motivated not by mental illness but by rage and vengeance.

If convicted of capital murder, Haskell could be sentenced to death.
