JULY 5--Swinging her five-month-old son like a baseball bat, a Florida woman yesterday struck her boyfriend with the infant before dropping the child face first into the sand on Daytona Beach, police charge.

Cops allege that Tatyana Allen, 18, initially hit her 19-year-old beau “several times in the face with a closed hand” before using her baby “as a weapon.” Allen, witnesses said, swung the infant “like a bat” before “the baby was dropped in the sand, face down.”

Allen’s boyfriend, the child’s father, quickly flipped the infant upright since he was unable to turn over on his own. Witnesses told cops that Allen subsequently “snatched” her son from the man’s arms and walked away with the child “dangling,” without his head being supported.

As Allen walked up a set of boardwalk stairs, the baby’s head hit a railing due to her "carelessness," according to the report, which notes that investigators got verbal statements from about 20 witnesses.

When questioned by cops, Allen accused the baby’s father of pushing her several times earlier in the day. While she copped to having “mushed” the man in the face, she denied throwing her child in the sand.

The baby was transported to a Daytona Beach hospital “for treatment and further evaluation,” police reported. The child was accompanied by an aunt, one of several family members present during the incident.

Pictured above, Allen was arrested for aggravated child abuse and battery. She is being held in lieu of $30,000 bond in the Volusia County jail. Allen lives in Ocoee, a city 10 miles from Orlando, and works at Dunkin’ Donuts, according to police records. (2 pages)
