MIAMI-DADE COUNTY, Fla. - Damaris Morejon said she received a shocking phone call. It was from Onelio Castro-Arroyo. She said he told her he had stabbed her 45-year-old cousin, Yanelis Gonzalez. He wanted her to know what he had done, she said Wednesday.

Castro-Arroyo also called police. The daughter he shared with Gonzalez was in the car. That didn't stop him from stabbing Gonzalez to death, police said. He is at the Turner Guilford Knight Correctional Center Wednesday afternoon facing charges in her mother's murder. 

Relatives said Castro-Arroyo, 51, and Gonzalez, who was born in Cuba's Pinar del Rio province, were in a difficult-to-leave marriage. Morejon said they had separated and were trying to get back together when they got into an argument. She said Gonzalez was considering getting a divorce.

Surveillance video shows Castro-Arroyo taking off his shirt -- which was stained with Gonzalez's blood --and dropping it with the suspected murder weapon into a dumpster, detectives said. He later told police officers the stabbing death was the end of a troubled relationship.  

Miami-Dade Police Department detectives started to investigate the domestic violence case inside of the parked black sports utility vehicle where Gonzalez died at the Country Club Villas Park at 6869 NW 179th St., north of Miami Lakes. 

Miami Police Department detectives assisted them in case. Castro-Arroyo surrendered with his hands up at the Villas of Havana at 717 SW 11 Ave., in Miami's East Little Havana, where Miami-Dade crime scene investigators also collected evidence on Tuesday.   

Miami-Dade Corrections records show Castro-Arroyo is facing charges of second-degree murder, tampering with physical evidence, grand theft, petit theft, criminal mischief and second-degree arson. He is being held without bond. 

Relatives said Gonzalez's adult daughter wants custody of Castro-Arroyo's daughter. Gonzalez's cousin, Ismay Ortega, set up a GoFundMe account asking for donations from the public to help cover the cost of Gonzalez's funeral and to help her two daughters.
