(Parker Co., TX)  —  A 20-year-old Springtown man is being accused of critically injuring his girlfriend’s infant son.

Kaleb Ray Eisenmann was arrested Friday for allegedly causing severe head trauma to the eight-week-old because he was crying.  Eisenmann was reportedly babysitting three young children while his girlfriend worked on Valentine’s Day.

Parker County investigators say the baby is in critical condition at Cook Children’s Hospital in Fort Worth and that staff at the hospital reportedly found bruises on the woman’s 2 year old daughter.  Eisenmann is being held in the Parker County Jail with bond set at $50,000.
