Denise and James Dimick's daughter, Brandy, died in her apartment just hours after her 32nd birthday party last November.
Her death has been ruled a homicide by strangulation, according to reports from the Medical Examiner.
"You see her in everything you do, every song that comes on the radio. For the first few weeks, I couldn't breathe, every breath hurt. To this day, I can't function," said Denise.
"It hurts like hell because I'm supposed to go first not my children," James said.
More than five months after her death, Pasco County Deputies arrested 34-year-old Wilson Dean Konkle, Brandy's ex-boyfriend.
They had children together.
Konkle is being charged with manslaughter.
Investigators say Konkle called 911 and attempted CPR. He claims he was having sex with the victim then she died shortly after.
"She should've never died that night. Never!" Denise said.
The Dimick family believes she was murdered. They say Konkle was upset after learning Brandy just got engaged to someone else three days before her death.
"No matter what the outcome, you did this, you put your hands around someone's throat and you took their very last breath," James said.
At Brandy's apartment, several residents tell us they heard screaming and arguing before the incident.
Her parents are also confused as to why Pasco Sheriff's Deputies had to investigate, when right next door is the Port Richey Police Department.
The Dimick's have their daughters name on their car windshield. Her mother wears a shirt with Brandy's picture. Her dad bought the front door of her apartment because friends all wrote heart felt messages on it.
James says he wants to make a table out of it for her 3 children. For now, he covers it up because he gets to emotional.
"It's hard to go on without her but i know i have to do it i just want justice for her, it's all i ask is justice for Brandy," James said.
Konkle has a criminal history. He served time for felony battery. His other charges include robbery with a firearm, burglary, and now manslaughter.
He's currently being held on $250,000 bond.
