MIAMI (Reuters) - A Cuban immigrant shot and killed four people including his estranged wife before taking his own life early on Sunday in Miami, police and local media said.
A sergeant with the Miami Police Department's homicide division who declined to give his name said the man, wielding a semi-automatic handgun, shot his victims inside a house in the city's Little Havana district shortly after midnight.
He then sped off in a pickup truck and turned the gun on himself at his home, which he had apparently set on fire, about 3 miles away.
"It was domestic-related," the sergeant said. "The wife left him and he tracked her down, unfortunately."
He declined to elaborate, saying the case was still under investigation.
But the Miami Herald said victims of the shooter, who had moved to Miami from Cuba about 10 years ago, included his wife, her daughter and her mother.
The daughter's boyfriend was also killed, according to the newspaper.
In Alabama last week, near that state's southeast border with Florida, a man shot and killed 10 people including his mother, grandmother, uncle and two cousins, before shooting himself dead.

Five people are dead following a murder-suicide in Miami, Florida today, after a man crashed a birthday party early Sunday morning. He informed the party-goers that they were responsible for his wife's decision to leave him, and then proceeded to open fire with a semi-automatic hand gun. The guests fled the scene into the street, or found cover.

The man, whom police identified as Guillermo Lopez, 48, immigrated to the United States from Cuba about 10 years ago. There were about a dozen people in attendance at the party. He killed his wife, who had left him, and shot her daughter, her daughter's boyfriend, and the boyfriend's grandmother. They were killed at approximately 12:15am in Little Havana, Miami.

Police first responded to the 2800 block of Southwest 38 Court following reports of gunfire. Four bodies were discovered behind the house.

"It was chaotic. I can't imagine what it was like in there," said homicide detective Ervens Ford.

Lopez fled the scene in a red Toyota Tacoma pickup truck to his home, which was about  from the original scene. He set both the house and truck on fire and committed suicide.

Police and firetrucks responded to a second 911 call regarding the blaze at the 700 block of Southwest 33 Avenue where the assailant's body was found with a gunshot wound.

The victims have been identified as Lazara Mendez, 50; Nayla Canfux, 19; Francisco Casas, 27; and Maria Lefran Christ, 77.
