An Ohio county corner says a woman who police allege was killed by her mother was suffocated.

A coroner and law enforcement held a news conference Wednesday to discuss the Tuesday arrest of 45-year-old Janet Tyburski. She is charged with murder in the death of 26-year-old Rachele Tyburski, whose body was found March 15 in North Ridgeville, west of Cleveland.

A police detective says authorities believe that Janet Tyburski killed Rachele on March 13 at the home they shared in Lakewood and that she dumped the body two days later.

Janet Tyburski was ordered held without bond. A judge is expected to assign her an attorney.

Her mother-in-law says Tyburski raised three daughters by herself after her husband died in 1999. She says Tyburski deeply cared for her daughter.
