It is actually the police department that stated it was murder-suicide by the mother. It appears they based this on what they found at the scene. They did not provide much information as is common in an ongoing investigation.http://www.dailymail.co.uk/news/article-3631535/Mother-killed-two-young-children-murder-suicide-amid-bitter-custody-battle.html
The article stated:
"There were no signs of stab wounds or gunshot wounds. An initial police report said it appeared to be a murder-suicide."
The fact that a gun or a knife was not used also increases the probability that she was the perpetrator. Men are statistically more likely to use guns or knives.
Surely there are still many open questions and undoubtedly the ex-husband will be investigated. However, given what information is provided and the initial police statement, I would put a higher probability on her being at fault.
