[Q]: Investigators say  Joseph Orbeso   22  shot and killed  his  girlfriend  Rachel Nguyen  20  and then turned the gun on  himself   according to a release Friday from the San Bernardino Sheriff’s Department Morongo Basin station.
 Orbeso  and Nguyen were reported missing July 28  after a bed-and-breakfast owner in the Morongo Basin told the Sheriff’s Department that they may have gone hiking in the park that morning.

"Based on evidence located at the scene  detectives believe  Orbeso  shot Nguyen  then shot himself. The investigation into  Orbeso ’s actions remains under investigation " the statement said.
The sheriff’s update comes days after  Orbeso ’s father  Gilbert Orbeso  publicly identified the pair and authorities said they were found in an "embrace."
"I want  Joseph  to be remembered as a kind  caring and thoughtful person "  his  father told the Southern California News Group in an email. "The way  he  was found beside Rachel holding her as they were seeking shade under the brush says everything you need to know about  him  as a man and as a human being."

[Q]: Actor John Bradley  who plays Sam  Tarly  told TV Guide that characters are going to keep being pushed by new elements and traveling the seven kingdoms deeper and faster than ever before.
"Each of the characters this year is placed in a completely alien environment at some point in the season that they've never been placed in before "  Bradley  said. "The thrill is seeing how they react to it and how they respond... This season  I think  more than any other is stretching these characters."
But  Bradley 's comments are intriguing from a character perspective. An alien environment isn't necessarily a physical place; it's an unfamiliar situation (Arya  no longer sniffing out traitors)  an important task (Cersei trying to play nice with others)  or a new threat (White! Walkers!).
"The stakes definitely feel ramped up  " Bradley  told TV Guide. "We know that we've got a real job to do. This has been a part of people's lives for so many years. This is our eighth season  and we are kind of feeling the pressure to get it right because we want to satisfy people...we just kind of want to give them an ending that they deserve."
[A]: Bradley

Bederow retorted that  David  has ­“repeatedly contradicted the sworn claims of  his  client as  he  seeks to promote [a] lawsuit.”
