Minnesota and federal authorities are investigating the alleged beating of a Mexican citizen by immigration officers last month, seeking to identify what caused the eight skull fractures that landed the man in the intensive care unit of a Minneapolis hospital.
Investigators from the St. Paul Police Department and FBI last week canvassed the shopping center parking lot where Alberto Castañeda Mondragón says Immigration and Customs Enforcement agents wrested him from a vehicle, threw him to the ground and repeatedly struck him in the head with a steel baton.
