At age 31, Nixon Arias cut a profile similar to many unauthorized immigrants in the United States. A native of Honduras, he’d been in the country for more than a decade and had worked off and on for a landscaping company for nine years. The money he earned went to building a future for his family in Pensacola, Florida. His Facebook page was filled with photos of fishing and other moments with his three boys, ages 3, 7 and 8.

But in November 2013, that life began to unravel.

The previous year, Arias had been mowing the median of Highway 59 just over the Alabama line when his riding lawnmower hit a hole, throwing him into the air. He slammed back in his seat, landing hard on his lower back.

Arias received pain medication, physical therapy and steroid injections through his employer’s workers’ compensation insurance. But the pain in his back made even walking or sitting a struggle. So his doctor recommended an expensive surgery to implant a device that sends electrical pulses to the spinal cord to relieve chronic pain. Six days after that appointment, the insurance company suddenly discovered that Arias had been using a deceased man’s Social Security number and rejected not only the surgery, but all of his past and future care.

Desperate, Arias…
