The 7-year-old Rhode Island boy whom officers named police chief for a day last month, received encouraging news this week in his fight against leukemia.

Tyler Seddon, who has been battling acute lymphoblastic leukemia for about four years, has found two umbilical cord blood matches. Tyler’s mother, Rachel Seddon, is hoping this will make for a successful stem cell transplant, the next step in her son’s treatment.

“It’s great news,” she said in a phone interview Friday. “It’s a perfect match.”

While Rachel Seddon expressed her own excitement, Tyler is not quite as happy, she said.

“I don’t know how thrilled he is,” she said. “It’s two months in the hospital. But I think we are both ready for this to be over.”


The Seddons continue to look for a bone marrow match for Tyler, which can lead to higher success rates and quicker recovery time. So far, the family has only found one match, but the person was unwilling to have a bone marrow donation from the hip, which is required in the procedure.

“We understand,” said Rachel Seddon. “But we would love to find a person for him.”

Tyler is to go in for surgery at the end of this month or early May, said his mother.

For his seventh birthday, Tyler had asked that emergency responders write him birthday cards.

His request moved firefighters, police officers, and emergency medical workers so much that about 1,000 of them came to his hometown of Burrillville, R.I., to deliver the notes and celebrate.
