The incident was reported about 4 a.m. in the Ryan Creek subdivision.

Police said Steven Lee Morgan, 37, whose last-known address is in Georgia, broke into the house armed with a knife, severely beat the woman and sexually assaulted her. He then fled in the victim's 1998 champagne-colored Ford F-150 pickup with license plate GE1221, said police Capt. John Grainger.

The victim was taken to Medical University Hospital with serious injuries.
