PHILADELPHIA — Authorities in suburban Philadelphia were investigating three suspected weather-related deaths Wednesday in the wake of a storm that dumped more than a foot of snow in some places and was accompanied by bone-chilling temperatures and icy winds.

Ridley Township police said a 93-year-old woman and an 89-year-old man died in separate incidents. Details on the woman’s death were not released, but police said the man had Alzheimer’s disease and died after wandering outside overnight during the bitterly cold snowstorm clad only in underwear.

The man’s family realized he wasn’t in the home and found him in a neighbor’s yard. He was rushed to a hospital, where he was pronounced dead.

Swarthmore police said a 67-year-old man’s death was suspected to be connected to the storm. No details have been released.

The Delaware County coroner will conduct autopsies on the three victims.

Residents faced a long, cold cleanup in the aftermath of the storm.

“We were hit pretty directly with the brunt of this storm,” Philadelphia Mayor Michael Nutter told reporters Wednesday, a day after about 14 inches of snow fell, prompting closure of city offices and early dismissal of public school students.

Philadelphia has gotten 33.7 inches of snow so far this season and for the first time ever has had three snowfalls of six inches or more before Feb. 1.
