Three-year-old Danyel was last seen inside her family's residence in the 1900 block of Manzanita Way in West Sacramento, California on November 2, 1985.
Her mother, Cynthia Sparpana was found deceased by police inside the residence on November 5, 1985; she had been dead for two or three days. She was the victim of a violent homicide; she had been beaten and shot in the back of the head. None of Danyel's belongings were missing from their home. Danyel has never been heard from again.
Lionel Ernest Tholmer Jr. was named as the prime suspect in the Sparpanas' cases shortly afterwards. He had been an acquaintance and sometime lover of Cynthia's. Authorities believed that Tholmer was also responsible for the November 1985 slaying of California resident John B. Meadows.
Meadows was Tholmer's ex-wife's stepfather and investigators believe Tholmer wanted to frame him for Cynthia's murder. Tholmer resided in Georgia, but he returned to the Sacramento area to work at McClellan Air Force Base in the mid-1980s. He was convicted of Meadows's murder in 1987 and was serving a life sentence for that when he was charged with Cynthia and Danyel's murders. At his trial, Tholmer's lawyers argued that he was innocent of Cynthia's murder and that Danyel had not been murdered at all.
There have been unconfirmed sightings of her since her mother's death. Tholmer was convicted of the Sparpanas' murders in November of 1992.
Danyel's remains have never been located and foul play is suspected in her case due to the circumstances involved.
Danyel has has a rust-colored birthmark on her right kneecap, approximately one inch by two inches in size. Both her ears are pierced. Her hair was short at the time of her disappearance.
