The shooting prompted a lockdown of both the daycare facility and the Catholic all-boys elementary school, and parents rushed to the area to pick up their children.
Detective Sgt. Al Bartlett said the man and woman who were killed worked together in what he described as financial transaction business.
“It’s our belief at this point that the altercation that took place is in relation to that business,” Bartlett.
“The person that we believe to be responsible is among the deceased,” he added.
He withheld the identities of the victims and the shooter, saying officials first had to notify their families.
Bartlett declined to comment on whether the suspect killed himself or died some other way, saying it was still under investigation.
Bartlett said no child was injured. He said there was no access within the building between the daycare center and the business.
Shahrokh Biniaz, a graphic designer and photographer who has a studio in the building where the shooting happened, said he heard a load bang and people arguing in the reception area.
