The husband of a Queensland mother found dead in suspicious circumstances near a ride-on lawnmower has been arrested.
The body of 49-year-old Frances Elizabeth Crawford was found at the bottom of a retaining wall on a property at Upper Lockyer, west of Brisbane, about 3.40am on July 30.
Detectives on Thursday arrested her husband, 47-year-old air force pilot Robert Crawford.

Police had previously said Mr Crawford was at the property on the night the mother-of-three died.
In a public appeal last week, homicide detectives asked people who had come into contact with Mr Crawford to come forward with any relevant information.
"Detectives can confirm a number of people have provided information since our last public appeal and thank those people for their bravery in coming forward," Queensland Police said in a statement.
