Officers went to the home on Talon Drive Monday afternoon and discovered her body. Detectives said the couple had a domestic dispute and Richardson killed her, but they did not say how.
Richardson is a veteran of the Iraq war. The 22-year-old had been a tank missile man assigned to the 2nd Marine Regiment, but the Corp dismissed him Wednesday.
Late Wednesday afternoon, 911 tapes were released in the case.
In his 911 call for help, he said he was suicidal before he allegedly killed his wife.
- 911: You wrote a note explaining everything?
- Richardson: Uh, it pretty much explains the situation.
- 911: Are you suicidal, sir?
- Richardson: Uh, I was. It was actually a suicide note, um, and I was going to follow through on it last night, uh...but I just could not...I couldn't bring myself to do it.
- 911: Did he say how he did it or anything?
- Caller: Uh, he said he had this note, that appeared to be a suicide note. Uh, telling that he did it...and that he had strangled her.
Even days later, Richardson's neighbors said they are still in disbelief.
"I saw all these cop cars and CSI, that's just something you see on TV not in Jacksonville where you live," Jacksonville resident Sarah Cisneros said.
Richardson's father told his hometown New Hampshire newspaper that his son lost several friends in Iraq and even suffered injuries himself.
A trial may eventually decide if Richardson suffered from any war-related trauma.
He's currently in jail under $1 million bond.
