The family of Tyre Sampson, the teen who fell to his death at an amusement park last week, say they’ve never met the woman who has repeatedly claimed to be his cousin.

According to the Sun Sentinel, Tyre’s mother told Florida authorities she doesn’t know who “Shay Johnson” is, nor does anyone else in her family. Authorities have since confirmed the woman’s real name is Lewishena Browning, a 32-year-old Orlando resident.
