Butler County authorities say a longtime teacher was wearing her seatbelt at the time of the collision that took her life on Tuesday night.
Initial reports stated that Hazel Dyer, 67, was not wearing her seatbelt when she ran a stop sign and collided with a pickup at the intersection of Southwest 20th Street and Boyer Road southwest of El Dorado just after 5:45 p.m. on Tuesday.
She was not breathing when emergency personnel arrived, and she was pronounced dead at Susan B. Anthony Hospital in El Dorado.
The 19-year-old man driving the pickup was not seriously injured.
"At the time of the accident, officers did not believe that the seatbelt was properly attached," Sheriff Craig Murphy said in a prepared statement.
It's not clear whether the seatbelt failed, Murphy said in an e-mail response to questions.
"All I can tell you is we have proof positive it was properly restraining her before the crash," Murphy said.
Dyer taught in the Bluestem School District for 32 years. A memorial service for her is set for 10 a.m. Saturday at the El Dorado Civic Center.
