A Leander man was arrested Friday on suspicion of a drunken New Year's sexual assault involving a woman he said he thought was his wife, a witness told police.
Brandon Lee Welch told police that he was very drunk that night and does not remember going to his neighbor's house or touching his neighbor's sister, but he did remember "something about being outside on the lawn," when he was "forced to go back home," the arrest affidavit said.
Police were called to a house in the 600 block of Meadow View early Jan. 1 to investigate the alleged assault.
A woman at the house told officers that she had fallen asleep in a recliner during her brother's New Year's Eve party and woke up to find a man standing over her with his genitalia exposed.
The woman told police she pushed him away and went for help, but the man followed her, pulled her pants down and began molesting her with his fingers, according to the affidavit.
The woman's brother told officers he walked in to find his sister pushed up against the kitchen counter with her pants down and struggling to get away from Welch, who lived next door.
When the brother confronted the neighbor, Welch reportedly "apologized and stated that ‘he was sorry, and he thought it was his wife,'" the document said.
Welch was released from the Williamson County jail after posting $15,000 bail on the felony sexual assault charge on the same day he was booked in.
