An 18-year-old male from San Antonio will be arraigned after confessing to striking his 4-month-old son, according to the Donna Police Department.

Donna police officers responded to Valley Baptist Micro Hospital on Wednesday in reference to a child with bruising to his facial area, according to a news release.
