$1 million reward offered Monday and arrest on Tuesday!
When he was asked by Nine News whether he murdered Michelle, Rumsby replied "no".
As he was led away in handcuffs he also claimed he had known Michelle's mother Loraine "for years".
He was charged with murder in the early hours of this morning and is expected to face Mudgee Local Court later today.
In recent years Rumsby has been living in Sydney near Windsor but lists the suburb of Kings Langley as his fixed address.
Rumsby's arrest comes after NSW Police offered a $1 million reward for information on Monday, with Michelle's mother begging the public for help.
