COLLIER COUNTY, Fla.- WINK News has brand new information that lays out a possible motive for the murder of a Collier County woman and her son.

Jose Suazo is in jail, accused of killing his wife and 18-year-old son in 2013.

Today, WINK News learned more about what friends and family members told investigators about the family, and what we are learning is giving us a better idea of what was going on inside that home and in Suazo's mind before and after the crime.

More than 300 pages detail the moments before, during and after the August 2013 murder of Johanna and Joseph Suazo inside their Naples home.

Interviews with witnesses describe their alleged killer, Jose Suazo, as an angry man, who they say repeatedly verbally abused and threatened his family. A counselor for the couple even told Johanna to move out, but Jose says it's their mistreatment of him that lead to the double homicide.   

Hours after Jose Suazo allegedly murdered his wife and son, he told deputies that "he didn't realize what he had done, he just lost it."

According to court documents obtained exclusively by WINK News, Suazo told friends his wife, Johanna, had a lover and when he confronted her, she didn't deny it. Suazo claims he saw emails between Johanna and a man from Honduras, whom she allegedly visited when her husband had heart surgery. The documents say Suazo told a friend on August 15th, the day of the murders, he had had enough.

A babysitter for the couple says that morning, Johanna dropped off the couple's two young sons, and confessed that "Jose was insulting her. They had been arguing all morning and Jose was calling her a whore." One hour before the crime, Suazo allegedly called a church member, saying "I'm going to kill her. I'm going to kill her." And after the killing, Suazo reportedly confessed to his pastor saying, "I did it because I couldn't take it anymore, too much mistreating."

Deputies say Jose Suazo then turned the gun on his older son, Joseph. Family and friends say the father and son often argued, with Jose calling Joseph "disrespectful." In witness testimony, a friend suggests Jose was jealous of the attention Joseph got from his mother. Suazo also claimed for years that Joseph may not have been his.

Suazo also allegedly argued with his wife about money, allegedly changing his life insurance policy over months before the murder because he didn't want his wife to get anything.

Suazo's next court date is in July.
