Witnesses say a District man grabbed his 18-month-old daughter by the neck, threw her into a table and beat her, then invented a story for doctors at Children's Hospital, where the little girl was pronounced dead, according to documents presented in court yesterday.

Irving A. Rudd, 23, of the 400 block of Florida Avenue NW, was charged with first-degree murder yesterday in the death of Tarricka LaPorscha Rudd and at a hearing in D.C. Superior Court was ordered held without bond.

Tarricka arrived at Children's Hospital last Thursday night with a cracked lip, a fractured skull and bruises all over her body, according to court testimony. Police found her twin sister at home, suffering from similar injuries and weighing just 10 pounds. The twin remains at Children's Hospital, where a spokeswoman said she is in fair condition.

In an affidavit submitted to support an arrest warrant, homicide detective Phineas A. Young summarized testimony by two unidentified witnesses to Tarricka's death.

Rudd allegedly hurled Tarricka's body into an end table, cutting her lip, then pounded on her chest with his hand, Young wrote.

According to one witness, Rudd then threw the toddler onto a sofa, saying, "Okay! You don't want to stand up, I'm going to sit you down on the couch," the affidavit said. The witness told Young that Tarricka lost consciousness when her head hit the wooden back of the couch.

Rudd told the witness that he would tell hospital officials that something fell on the baby to avoid "get{ting} in trouble," according to the affidavit.

Tarricka was the 12th child to die in the District this year of suspected abuse and neglect, twice the number from all of 1991.

The twins and their three siblings, ages 6 months, 3 and 5, lived with their mother, Tawanna Williams, Rudd and an aunt, according to court documents. The surviving children have been placed in city custody.
