OCOEE, Fla. — One woman was killed and another injured in a shooting Monday morning at an Ocoee home in what police think was a deadly domestic dispute with a man.

• 1 killed, 1 injured in shooting at Ocoee home
• Investigators: 2 women shot by man who killed himself
• Shooting victim in hospital talking with police, they say
• Police not looking for any other shooting suspects

Ocoee Police were executing a search warrant later in the day at the home on the 2300 block of Grand Poplar Street, in a residential neighborhood a few blocks southeast of Clarcona Ocoee and Clarke roads.

Investigators think the older woman killed inside the home, 52-year-old Marie Alexandre, was the stepmother of the younger woman who survived the shooting and was hospitalized. That woman was identified as Marie Pierre, 22.

Pierre told 911 dispatchers that her boyfriend shot her and her mother.

The suspect in the case was the younger woman's boyfriend. There was some kind of argument, and after the shooting, the suspect took off while the younger woman ran outside and called 911, investigators said.

"We believe this is a domestic, girlfriend-boyfriend situation, but we don’t know the exact details of how it turned violent," Deputy Chief Stephen McCosker of Ocoee Police said. 

"As I was coming out the front door, I heard screaming down in this direction, and I didn't think anything about it, because I know people can be having an altercation or something," neighbor Mike Crampton said.

Then "I walked my dog down this way, and I noticed a young woman in the yard. She was talking on the phone... very loudly.

"So I went down the block, and as I was coming around the corner here again, about that time, a little bit after that, about four police cars pulled up and pulled their weapons out, and they ran up," Crampton said. 

Police said Marie Pierre was shot in the head but was alert and talking with investigators at the hospital.

During an almost seven-minute phone call to 911, Marie Pierre told dispatchers that she thought her boyfriend took off and was headed to his home in Haines City in Polk County.

Her boyfriend, 23-year-old Pierre Bernard, was found dead at the Haines City home from an apparent self-inflicted gunshot wound, police said.

"We do have an active investigation going. Even though the suspect is deceased, we’ll be going through that fully," McCosker said. 

Completely distraught with his mother's death and sister's hospitalization, Yvsmike There, the son of Alexandre, struggled to find the words to describe his mothers death. 

"I can't find the words to explain to you exactly how it feels ... It's not easy. I try to talk about her before, but talking about her like that -- it's more painful every time I try to say something like that." he said.

There said his family is surviving with the support of their church in Pine Hills -- Ebenezer Baptist Church.
