>>> it had been only an hour since josh hilberling died in a horrifying fall from a 25th floor apartment. his wife amber was now at a downtown police station with her grandmother gloria. filled with questions that had no good answers.
>> how did this happen? why did he have to fall out the window? i didn't just lose my husband. jeannie and patrick lost their son. zack lost his brother.
>> airman first class zak hill ber ling, josh's younger brother was serving a tour in afghanistan. he got the news when he logged on to facebook.
>> i called my dad and it was late, 11:00 or 12:00 . the fact that he answered the phone blew my mind. i think the first thing that i said to my dad, tell me that it's not true. but he said it is.
>> zack headed home as the hilberling clan gathered in tulsa to mourn and remember.
>> joshua was my first-born son. he was everything.
>> josh's father patrick and stepmother jeannie.
>> he had a smile. i mean, he could light up a room.
>> i called him joshie. i don't think anybody else is allowed to call him that.
>> is he a mama's boy?
>> he's been accused of that. he'd help me cook and things like that. he had a tender side.
>> that tender mama's boy grew into a strapping 6'4", 220-pound teenager. a star on his high school football team. for an oklahoma kid, that was a very big deal .
>> josh, football was the most exciting friday nights.
>> he was a phenomenal football player. that was his sport and his game. that's his first love.
>> it was back in 2008 when josh met amber at a halloween party. once they started dating, he literally swept her off her feet.
>> what are some of the things he did for you?
>> one night he drove me out to a basketball court at a park in his parents' neighborhood and i didn't know how to dance. so he put me up on his -- the tops of his shoes and danced with me under the stars.
>> things were perfect at first. aren't they always.
>> we were young, passionate. it was nice.
>> josh and amber had been dating for just a few months when he got his marching orders. he was assigned to an air force base in alaska. the young couple faced a crossroads. they wanted to be together so they arranged a quick courthouse wedding. followed later by a lavish country club reception.
>> it was so dorky. i almost passed out i was so nervous. we were both kind of giggling at ourselves more or less.
>> you sound like two teenagers.
>> i mean, yeah, we were.
>> but now amber was at a tulsa police station , no longer a giggling teenage bride. she was a widow and filled with anguish as she poured her heart out.
>> just come back, please. please. i love you. i love you so much.
>> but through the fog of her grief, a story started to emerge. amber told her grandmother she and her husband had been arguing and now she couldn't believe how it ended.
>> no he's not supposed to be. but he's in god's hands.
>> not fair.
>> throughout their gut-wrenching conversation, amber and her grandmother were alone in a police interrogation room talking in confidence, or so they thought. it turns out officer don holloway had been listening the entire time.
>> i was in the other room typing up my report and all of a sudden amber started talking about what had happened.
>> so holloway started recording the conversation. every word, every gesture was being captured when amber said something that would change everything.
>> he was like messing with the tv right here. and the window is right here. and i pushed him and he fell into the window, fell. oh, god.
>> and when through her tears amber said she had pushed josh, her grandmother seemed to sense the gravity of what the words might mean to police.
>> quit saying you pushed him out the window. did you intentionally push --
>> no. of course not.
>> okay. that's what they're going to take it as, baby.
>> was amber 's grandmother right? would homicide detectives think the overwrought teenager was talking about an accident or was she describing something much darker?
