Anthony Serges Poulin, who is accused of raping and drowning a 5-year-old girl on Sunday, is scheduled for a preliminary hearing today in Hilo District Court.

Poulin, 30, of Wainaku, is charged with second-degree murder, two counts of first-degree sex assault plus abuse of a family/household member in the death of Javieanne Win. He is being held on $1 million bail.

Win was a first-grader at Chiefess Kapi'olani Elementary School. Several of her neighbors and family, including her mother, Jennifer Abiley, saw Poulin's initial court appearance on Wednesday.

Abiley was not at home and Win was in Poulin's care when police and paramedics responded to a 3:06 p.m. call of an unresponsive child in a filled bathtub in the family's Pu'u'eo Street apartment. An autopsy found that Win's death was a homicide by "asphyxiation due to forceful submersion," said police Capt. Randall Medeiros, head of the Criminal Investigation Section.

Less than 40 minutes before emergency personnel went to the apartment, police received a call about a man abusing a girl at Shipman Street and Kamehameha Avenue in downtown Hilo.

A court affidavit written by police Detective Reed Mahuna said a woman "reported witnessing Poulin grab the victim by the hair, spin her around and slam her violently into the cement side of a building face first."
