I think the whole thing was planned myself.
The father coming over with the family heirloom baseball bat purportedly as a gift for the little boy. What a coincidence. His story of hearing bumping upstairs and grabbing the baseball bat to go up there is just complete bollocks. Why would you do that? If you heard what you thought was an altercation between husband and wife, you'd bang on the door, shout instictively 'leave my daughter alone' or whatever, get your wife to call the police, call the police yourself ... something other than go in there swinging a baseball bat you just happened to have brought with you ... and crushing someone's skull and scalping them at the same time. All this while your wife and two kids apparently slept through the whole thing - this violent struggle with this gigantic murderous Irishman.
Molly Martens had telephoned Jason's sister back in Ireland a few months prior to find out when Jason's father's 80th birthday celebrations would be taking place (in Ireland), as Jason planned to attend with the children. She thought it odd at the time - why wouldn't Molly just ask Jason?
The killed him a matter of weeks before he was due to travel to Ireland with the children. He had already confided to others he was homesick and unhappy in America. I think she was petrified he was going to go with the kids and not come back.
I think it was planned and premeditated. There were numerous calls that evening between Molly and her parents before they even arrived. I think Jason had a few beers with the neighbours and was out for the count. As he slept she lumped him with the brick. Then the father came in as they'd planned, and together they beat the crap out of him.
Then they sat there while his blood concealed and body went cold and got their stories straight before calling the police.
Apart from blood spatter there was no sign of the struggle they claimed. Neither one of them had a mark on them and he was beaten so badly when the paramedic attempted first aid, his hand went straight through his skull. Molly apparently kept rubbing her neck so obviously and persistently (to reinforce the claim she'd been choked even though there was so sign, no mark, no bruising) that it started to get on one of the investigating detectives nerves and he told her to stop.
