There was no evidence of a break-in, but investigators said they did find damage to a front glass door indicating a breakout.
Authorities have not released the names of the victims pending notification of next-of-kin. The causes of death have yet to be determined, but detectives said they suspect foul play. Investigators provided little information about the case.
