Police: Arrest in deaths of girls, stepdad in Ark.

ARKADELPHIA, Ark. (AP) - A 19-year-old has been arrested in connection with the killings of 2 girls and their stepfather in Arkadelphia, Arkansas State Police said late Saturday.

Riakos Lizana of Arkadelphia was arrested about 9:30 p.m. Saturday at a local apartment complex on a warrant in the case, state police spokesman Bill Sadler said in an emailed statement.

He didn't elaborate, adding in his statement that no further information was expected to be released about the investigation prior to Lizana's first-appearance hearing in coming days.

A suspected cause hasn't been released in the deaths of 40-year-old Bobby Jean Galbraith, 4-year-old Marley Crutchfield and her 6-year-old sister Adiele Crutchfield.

Police said the bodies were discovered Thursday evening when the mother of the girls - Anna Galbraith- arrived home that night and called police after finding her husband dead.

Police said a 6-month-old girl, reported to be Bobby Galbraith's biological daughter, was found unharmed when officers entered the home.

Sadler said in his statement that special agents with the Arkansas State Police criminal investigation division had been working non-stop since Thursday on the investigation along with counterparts from the Arkadelphia Police Department and Clark County Sheriff's deputies.
