Police believe a Florida man fatally shot his wife and his wife’s sister Sunday morning before turning the gun on himself.

The Palm Beach Post reported that Julien Techeler Rosemberg, 44, allegedly used a semi-automatic handgun to shoot his wife, Pierrena Rosemberg, 43, and her sister, Lourdine Cazeau, 41, multiple times. Police said he then walked to the backyard and used the same weapon to fatally shoot himself.

Police received a call shortly before 6 a.m. but it’s not immediately known who placed the call. All three adults were pronounced dead at the scene, according to the Sun-Sentinel.

Delray Beach Police spokeswoman Dani Moschella revealed that the couple’s three children and Cazeau’s child were home at the time of the shootings. The four children, who range in age from 5 to 14, were not injured but had to run past the victims’ bodies as they fled the home.

Wesner Louis, a cousin of the two slain women who lived nearby, told WQAM that Pierrena was sleeping in bed when Julien shot her in the head.

With a motive not yet known, police mentioned that there were no previous calls to the home for violence.

“Pierrena is a good lady. Working hard, seven days, go to school, after come home and take care of the kids,” Louis told the news station, adding that the couple appeared happy and had been married for more than 20 years.

“That surprises me. They always loving, kissing, happiness.”

However, one relative told the Post that all three came from Haiti and described the couple’s turbulent marriage—which included prior instances of Julien threatening to kill Pierrena. The relative, who wished to remain anonymous, said Pierrena was not alarmed by her husband’s threats.

The police spokeswoman said that all four children are staying with relatives.
