From the news story:
"The two argued through the day over the attention Smith was paying her and their relationship. While in Smith’s dorm room and “feeling extremely emotional and stressed,” she told police, she boiled a pot of water. Then, she walked over to Smith and poured it on him.
When Smith didn’t react strongly enough for her, she started hitting him with her open hands, she told police. The extent of the burns aren’t known, but Smith has been seen back on campus even though he’s not fit for the football field.
