A South Florida mother and her 5-year-old daughter have died after being found unresponsive in an apartment complex pool, the AP reports. Local news outlets report that Coral Springs police say 32-year-old Heidi Geselle Marrero and Joneily Lanclos, 5, were discovered face down in the pool Sunday afternoon and were unresponsive when they were pulled out. Both were taken to a hospital, where they were pronounced dead. Police spokeswoman Sgt. Carla Kmiotek says they're working to figure out how both of the victims ended up in the pool. Marrero was found fully clothed and her daughter was wearing a swimsuit; both had been underwater for more than an hour. (More drowning stories.)
