A Bucks County woman faces charges after her three-year-old grandson was found wandering along a street. 48-year-old Lisa McLawhorn of Wicker Avenue in Bensalem is charged with endangering the welfare of a child and recklessly endangering another person. Court documents say she got drunk while babysitting Monday and the boy got out through an open window. A passing motorist stopped after seeing him wandering along Brown Avenue outside the Regency Apartments, where McLawhorn was watching the boy and his nine-month-old sister at her daughter’s apartment. The motorist called police, who found McLawhorn after about 40 minutes with an open can of Natural Light beer sitting on a nearby end table. Her blood alcohol level was more than 0.13, well above the legal limit for driving. She said her grandson was watching TV in his room, and she admitted not looking in on him for nearly two hours. She also admitted having a drinking problem.
