Before bed one night, Tina Case was on Facebook when she read this post from a friend 40 miles away: "If anyone is up, PLEASE call 911 for me! My phone isn't working and I think someone is in my house!!!” After trying her friend's home phone with no luck, Case called 911. When police verified the emergency and discovered her friend's phone lines were dead, they sent officers to the house. Her friend was OK and authorities later said the appearance of police may have thwarted the intruders.
