From the Des Moines Register:
The man accused of throwing a McChicken sandwich at his wife reportedly broke the woman's nose during the incident, police said Thursday.
Sgt. Jason Halifax, a spokesman for the Des Moines Police department, confirmed that Marvin Tramaine Hill II, 21, did more damage than police initially thought after smashing a sandwich bun into his wife's face Tuesday afternoon. Halifax said charges against Hill will likely be amended to simple domestic assault causing bodily injury.
"It doesn't matter what instrument is used to commit the assault ... ," Halifax said. "Domestic abuse is a huge problem. The greater issue is this guy is getting angry over a sandwich."
