SIOUX CITY, Iowa (AP) – A 25-year-old Sioux City man who’d been tracking his estranged wife has been convicted of interstate stalking and a weapons charge. Federal prosecutors say Ralph Rogers was convicted last week. The jury acquitted Rogers of kidnapping and another weapons charge. Rogers pleaded guilty in September to another weapons charge.  His sentencing has not been scheduled.

Prosecutors say Rogers had secretly placed a GPS device on his estranged wife’s car. Investigators say that when the tracking device showed that she’d stopped at a residence in South Sioux City, Neb., Rogers got a handgun and drove there.  Prosecutors say Rogers entered the home without permission and assaulted one of the people inside. Prosecutors say Rogers then took his estranged wife back to his home in Sioux City.
