Authorities in Arizona believe a woman was suffering a fatal medical episode when she collapsed on her 4-month-old son — suffocating him.

KTRK and KPHO reported that Tempe police discovered the bodies of Larinique Meadows, 38, and her son, Denari Meadows, after receiving a call to their home on Saturday afternoon. The infant’s father reportedly claimed he was sleeping upstairs after working a late shift and woke up to find the pair dead.

An investigation revealed that Larinique Meadows had searched symptoms regarding chest pain on her phone but she did not call 911. Her phone was reportedly located near her body.
