Here are 2 scriptural examples of God using the Holy Ghost to intervene and protect one of his children...
16 And it came to pass that when I, Nephi, had spoken these words unto my brethren, they were angry with me. And it came to pass that they did lay their hands upon me, for behold, they were exceedingly wroth, and they did abind me with cords, for they sought to take away my life, that they might leave me in the wilderness to be devoured by wild beasts.
17 But it came to pass that I prayed unto the Lord, saying: O Lord, according to my faith which is in thee, wilt thou deliver me from the hands of my brethren; yea, even give me strength that I may burst these bands with which I am bound.
18 And it came to pass that when I had said these words, behold, the bands were loosed from off my hands and feet, and I stood before my brethren, and I spake unto them again.
(1st Nephi Chapter 7)
52 And it came to pass that I, Nephi, said many things unto my brethren, insomuch that they were confounded and could not contend against me; neither durst they lay their hands upon me nor touch me with their fingers, even for the space of many days. Now they durst not do this lest they should wither before me, so powerful was the Spirit of God; and thus it had wrought upon them.
53 And it came to pass that the Lord said unto me: Stretch forth thine hand again unto thy brethren, and they shall not wither before thee, but I will shock them, saith the Lord, and this will I do, that they may know that I am the Lord their God.
54 And it came to pass that I stretched forth my hand unto my brethren, and they did not wither before me; but the Lord did shake them, even according to the word which he had spoken.
55 And now, they said: We know of a surety that the Lord is with thee, for we know that it is the power of the Lord that has shaken us. And they fell down before me, and were about to worship me, but I would not suffer them, saying: I am thy brother, yea, even thy younger brother; wherefore, worship the Lord thy God, and honor thy father and thy mother, that thy days may be long in the land which the Lord thy God shall give thee.
(1st Nephi Chapter 17)
I'm guessing that the 9 year old girl in the OP just wasn't as important to the grand scheme of things as Nephi..
