NEW ORLEANS (AP) — An Orleans Parish jury has convicted Ryan Poree in the deaths of his neighbors, siblings Kimberly and Alcee Perry, who were shot to death outside their eastern New Orleans home in October 2011.

The Times Picayune reports that the jury Friday rejected Ryan Poree's arguments that he is insane.

Poree was convicted of two counts of murder, one count of attempted murder and one count of obstruction of justice, for hiding his rifle after the murders. He faces a mandatory sentence of life in prison without the possibility of parole when sentenced March 14.

Authorities say a 7-year-old nephew was wounded with gunshot wounds to the leg and abdomen.

Prosecutors deny that Poree was insane and say testimony from at least three doctors bolstered their conclusion.
