HOUSTON (AP) — Investigators say a drifter charged with capital murder in the 1993 slaying of a retired Texas teacher has been extradited from Mexico.

Alfredo Ramirez-Rosas was being held without bond Thursday a day after being returned to Houston. Prosecutors waived seeking the death penalty so that Mexico, which does not have capital punishment, would allow extradition.

Authorities say 82-year-old Mildred Stallones of Tomball was attacked in her home by an intruder. She was beaten, strangled and sexually assaulted.

A warrant was issued for Ramirez-Rosas, described by police as a drifter and day laborer, after clothing found in his nearby home had the victim's blood on it.

Investigators believe he fled to Mexico hours after the killing. Ramirez-Rosas was arrested in 2013.

Online records don't list an attorney to speak for him.
