AUSTIN, Texas (AP) - A Central Texas man accused of fatally beating his girlfriend and kidnapping her daughters has been sentenced to 45 years in federal prison.

Terry Allen Miles was convicted in February of several charges, including two counts of kidnapping. He was sentenced Tuesday.

Authorities discovered the body of Miles' 44-year-old girlfriend in a welfare check at their home in Round Rock near Austin in December 2017, after she didn't turn up to work.

Investigators have said Miles fled with the girls, then aged 7 and 14, and sheriff's deputies caught up with them a few days later in Colorado. They said Miles had been sexually assaulting the teenager for five months.

Authorities believe Miles beat his girlfriend to death but he has not been charged in her death.
