AKRON, Ohio -- An off-duty Canton firefighter and her husband of nine days argued about the "kinks in their relationship" before she stepped out of a car and walked into the rush hour traffic on Ohio 8.

Tonya Johnson, 43, and her new husband ran errands Monday in and were on their way home about 4 p.m. Monday on Ohio 8 southbound when they ran into stop-and-go traffic, according to the Summit County Medical Examiner's report.

Johnson's husband told investigators they talked about how to work out the problems in their relationship.They also argued about the traffic on the highway.

He tried to pull off the highway once but traffic started to pick up again so he drove back onto the highway. Johnson told him to exit.

The husband pulled towards the exit again, when Johnson got out of their Cadillac Escalade. She walked behind the SUV, then across three lanes of southbound traffic.

She jumped over the cement median. She walked into the northbound lanes and stopped, according to the medical examiner's report.

A car swerved and missed her. The pickup behind that car hit her. The impact sent her flying through the air. Her shoes ended up in the southbound lanes.

Ten cars crashed trying to avoid hitting Johnson. No one else was seriously injured.

Johnson's husband told investigators that his wife skipped two days worth of medication for a mental health disorder. She had taken the drugs on Monday, the report says.

Johnson's sister, however, refuted that. She told investigators that she was not on medication for a mental health disorder, but that she had been under stress because of relationship problems.

The report lists Johnson's death as a suspected suicide. The medical examiner has not made an official determination. Akron police said they are still investigating.

Johnson was a 17-year veteran of the Canton Fire Department. Canton Fire Chief Thomas Garra said she was a well-liked and respected firefighter and medic.

She married her husband on Feb. 13, according to Stark County court records.

Her ex-husband, James Johnson, said she had two adult children and a 12-year-old daughter.
