The Salt Lake County Sheriff's Deputy was found dead in her bedroom at the Utah home she lived at with her father on August 1.
An autopsy revealed Martinez died by strangulation.
Her body was found at around 8:20 am that morning as cops did a welfare check after her mother and uncle raised concerns about her.
"Blood was observed in the victim's mouth and there were visible apparent fingernail claw marks on the victim's face and neck," investigators said in court documents, per .
The court docs included a disturbing text message Martinez-Ayala sent to his brother just after 4:30 pm on July 31, a couple of hours after his daughter returned home.
"My brother, you know (how) much I love you, I made a big mistake, an unforgivable sin," he wrote.
"I'm too scared and I don't know what to do. I think I will never come back."
Investigators called him an “obsessed and controlling dad" whose text messages were more like those “of a jealous lover than a father."

Police said in February, Martinez found a bag of her underwear in her father's bedroom.
His odd behavior toward his daughter allegedly escalated this summer when he "purchased a tracking device and hidden spy cameras."

In July, he placed the tracking device on Martinez's car, court documents claim.
Investigators believe the situation came to a head on July 29, two days before Martinez's death.
Her father allegedly tracked her to Bates Canyon, where she was with "her romantic interest" and this caused an argument between the dad and daughter.
Martinez didn't return home and chose to stay in a hotel instead, until July 31, the day she died.

MOTHER'S INSTINCT
Martinez's mother Barbara Jimenez, who lives in Belize, believes her ex-husband killed her daughter.
Jimenez, who had daily contact with her daughter, said Martinez argued with her father two days before her body was found.
On July 31, she told her mother that she was not feeling well and was planning to call in sick to work.
"The last message I had from her was around 2 pm," Jimenez told .
Growing concerned, she contacted her ex-husband who told her their daughter was at work.
"He stopped answering me," Jimenez said.
She continually tried to contact her daughter and ex-husband before turning to her former brother-in-law, who said he would check in on the pair.
He also called the police to request a welfare check on his niece.
Martinez's uncle eventually called her mother to tell her cops discovered Martinez's body - and that her ex-husband was nowhere to be found.
“When Marbella’s uncle called me, he just said, ‘I’m so sorry’ and I knew it. I could just feel something had happened to my daughter,” Jimenez said.
"I know Hector did something to her. He has a temper sometimes... We know he killed her.
"I just want justice for my daughter. She was beautiful and kind and had the rest of her life to live."
