Hurricane Maria leaves trail of devastation
MOROVIS, PUERTO RICO - DECEMBER 20:  A resident, whose home remains without electricity, watches as debris is removed on December 20, 2017 in Morovis, Puerto Rico. Barely three months after Hurricane Maria made landfall, approximately one-third of the devastated island is still without electricity and 14 percent lack running water. While the official death toll from the massive storm remains at 64, The New York Times recently reported the actual toll for the storm and its aftermath likely stands at more than 1,000. Puerto Rico's governor has ordered a review and recount as the holiday season approaches.  (Photo by Mario Tama/Getty Images)

Trees, fences fall as Maria hits Puerto Rico
Residents of San Juan, Puerto Rico, deal with damages to their homes on September 20, 2017, as Hurricane Maria batters the island. 
Maria slammed into Puerto Rico on Wednesday, cutting power on most of the US territory as terrified residents hunkered down in the face of the island's worst storm in living memory. After leaving a deadly trail of destruction on a string of smaller Caribbean islands, Maria made landfall on Puerto Rico's southeast coast around daybreak, packing winds of around 150mph (240kph).

Hurricane Maria pummels Puerto Rico
Aguas Buenas, Puerto Rico CNN —  

Miguel Olivera, now 75, survived combat and being impacted by Agent Orange in Cambodia as the US waged war against the Viet Cong decades ago.

Now, at home in Puerto Rico, he is facing another threat to his life – a fridge without power.

He needs insulin to survive but his last vial is sitting, at risk of spoiling, in that refrigerator that can no longer keep it cool.

Miguel Olivera and his wife Diana Aponte show a picture from his time in service.

Miguel Olivera and his wife Diana Aponte show a picture from his time in service.

His town, Aguas Buenas, in the mountains above San Juan, was left tattered by Hurricane Maria.

The lush tropical foliage is gone – as if a massive lawnmower came from the sky and shredded it all.

Olivera and his wife Diana Aponte, 73, sheltered from the storm inside their home – it’s built on concrete stilts sunk into the hillside, and Aponte feared it would slide into the ravine.

Weir in Puerto Rico: Looks like bomb went off

Water came through the shutters as the wind howled outside, and at one point the couple huddled on the living room floor, prepared to die together.

“The hurricane is worse” than combat, Olivera says.

A massive electricity power tower crashed next to the couple’s house – cutting the town off from help, as well as knocking out power for who knows how long.

Aponte is still shaken by what they went through when Maria crashed ashore and by the crisis they see no way out of. Yet she still insists on making a perfect café con leche for visitors.

“I can’t describe the storm. I’ve never seen anything like it in my life,” she says. “I thank God I’m still alive.” All her fears now are for her husband, and that insulin in the fridge.

It’s just one story among so, so many of families devastated and struggling in Puerto Rico.
