Crime Texas Mom's Body Discovered by Her 5-Year-Old Daughter; Ex-Boyfriend Charged with Murder Shereena Ann Webster was killed on August 18, and authorities have charged her ex-boyfriend with murder By Steve Helling Published on August 24, 2022 03:15 PM Share Tweet Pin Email A young mother in Amarillo, Texas was shot to death on August 18 — and authorities now believe that her ex-boyfriend killed her. Shereena Ann Webster's body was found by her 5-year-old daughter shortly after 5 a.m. The little girl contacted her grandmother, who then called 911. When officers arrived at the scene, they determined that Webster, 36, had been shot to death. According to property records obtained by ABC-7 News, Webster had closed on the home in February. Several homes in the brand-new neighborhood were not yet completed. But according to an arrest affidavit obtained by NBC 4 News, at least one neighbor's surveillance cameras were working. The neighbor provided video to police that appeared to show a vehicle driven by Webster's ex-boyfriend, Erik Mitchell Rivas. The vehicle arrived at the scene just after 3 a.m. and stayed until after 4:15 a.m. Webster's body was discovered less than an hour later. Shereena Ann Byington Webster.

Her mother told police that her daughter "was scheduled to leave town on or about Aug. 19 to meet a romantic interest in Colorado." PEOPLE confirms that Rivas has been arrested and charged with one count of murder. He is being held at the Wise County jail on a $500,000 bond.
