HAYSVILLE ? One woman was killed and her husband and grandson were injured in a stabbing early Sunday at a Haysville mobile home park, police said.

Tonya Dudley, 43, died of stab wounds at the Peachwood Manor mobile home park, said Haysville police Capt. Bruce Powers. Her 47-year-old husband, Jack Dudley, and 5-year-old grandson, whose name was not released, were hospitalized in serious condition, Powers said.

The couple’s 25-year-old son has been arrested, but no charges were expected until Tuesday, Powers said.

No motive was immediately available, but the authorities said they had responded to domestic disturbance calls at the mobile home in the past.
