HOUSTON (CBSDFW.COM/AP) — Prosecutors brought a more serious charge Monday against a Houston man in connection with the death of his ex-fiancee’s 4-year-old daughter.

The Harris County District Attorney’s Office charged Derion Vence with causing serious bodily injury to a child in the death of Maleah Davis.

The count carries a potential life sentence.

Vence has been jailed since May on the less serious charge of tampering with evidence, which carries a maximum sentence of up to 20 years in prison.

A district attorney’s office spokesman says a murder charge is “not off the table.”

Maleah was missing for several weeks before her remains were found by an Arkansas highway in May.

Vence had told police she had been kidnapped by assailants who had let him and his 2-year-old son go.

Vence’s attorney declined to comment Monday.

Medical examiners ruled Davis died from “homicidal violence” after her remains were found in May in Arkansas.
