PHOENIX – Authorities said Monday they believe a Tempe woman died of a heart ailment over the weekend and then slumped over on her baby, smothering the boy.

Larinique Meadows, 38, apparently had been searching for information about symptoms on her phone before her death Saturday, Tempe Police Detective Greg Bacon said during a press conference.

Bacon said there were no signs of injuries in 4-month-old Denari Meadows, and it’s believed he died of suffocation.

“She was researching chest pains, so it’s a very, very tragic incident in which we believe that she had some kind of heart condition … and then passed away and fell on top of Denari,” Bacon said.

He said the medical examiner’s office will make the final determination on the causes of death.

The baby’s father, who works nights, was asleep upstairs when the deaths occurred.

The father last saw the mother and son around 11 a.m. and woke up to find them dead around 5 p.m., Bacon said.

The mother was on top of the baby, and her phone was nearby, he said.
