José David Murcia Valdez, a 30-year-old Honduran refugee, fled Honduras six years ago after a machete attack cost him a finger and left scars across his arms and shoulders. He settled in Monterrey, Mexico, and worked for three years at a recycling plant until Mexican authorities arrived to check employees' papers and deported him back to Honduras. Unable to remain in Honduras because of the earlier attack, he returned to Mexico and joined a migrant caravan called Sueños sin Fronteras, attempting to bike more than 1,000 miles back to Monterrey in search of work.
