A woman, upset over her boyfriend coming home from work without money the couple needed, took out her frustrations on her 10-month-old son, sending the baby to the hospital in critical condition, according to court records and police.

Prince George’s County police on Monday arrested 20-year-old Jacqueline Vanessa Diaz-Pineda of Adelphi on first- and second-degree child abuse and assault charges after she admitted to abusing her infant son, authorities said.

Police said they were called to Diaz-Pineda’s home in the 9300 block of Lynmont Drive just before 7 p.m. Monday for a report of an infant “suffering a medical emergency.” The infant was rushed to a hospital in critical condition with a skull fracture and bruises all over his body, according to charging documents.

Diaz-Pineda admitted to “shaking the victim and throwing him against the wall,” court records continued.

“The defendant advised . . . that she was upset when her boyfriend came home from work and told her he was not able to get the money they needed,” charging documents state. While her boyfriend was in the shower, “she took her frustration ‘on the baby.’ ”
