Seemingly one of his great passions in life was golf (& rugby), he was a member of a golf club. His locker at the club was searched, it is detailed on the Search Warrants. As this was the same time as the other searches I got the impression that they were dotting their i's & crossing their t's in their search for a baseball bat. MM commented on her page that they were looking for a golf club, she only refereed to it as a 'I don't know why they want a golf club', she was referring to the Guardian searching her house. My opinion of this was the people in the area would have got wind of the search and she was trying to pass it off that the guardians were looking for a golf club.
Edit - The search of the locker was actually on 18th August, not the time of the search of the house as I implied above, sorry. There were not actual items detailed on the warrant, it was requested to find anything which could relate to the crime. The warrant was however at the same time they issued the warrants for the wireless records, AT &T. The searches for google were instructed on 4th September and the search of the property was issued on 4th December. Bank search warrants were 17th September. Laptop search warrant was on 3rd September. Facebook was on 4th September.
Also, her own Lawyers stated that all the neighbours thought that the children were her natural children.
