Robbed of mother's burial money

My mother Marie Orange was put on life support Sunday 9/17/17 after being discharged from hospital too early. She had mini seizures which lead to no oxygen to her brain. It took 7 minutes for the paramedics to arrive.
My daddy Melvin Orange said that I should come to Memphis asap.
 I arrived at the airport at 1:30pm on 9/20/17 and rushed to my mom's bedside at the hospital. I stayed for 2hours then hurried to find my dad. My dad has lost his will to live because he says he can't live without his wife. The doctor said it was costing $55,000 a day to keep her on life support and so my dad decided to sell the house although it was worth more than $20,000 he signed the papers anyway because he wanted my mother to have a proper burial.
$8,000 went to back owed taxes so my dad came home with $12,000 . 
I verified that the money was there and we we're about to discuss arrangements when at 7:40pm or a min later, two guys masked and armed busted into the house holding guns to my little sister Linda Orange head by the door rushing down the hall demanding the money the knew what bag to look for and the amount he took the bag beside me from the bed then I ran after him and grabbed the bag of money and he held a gun to my head and said he would shoot me and kill me I screamed and cried begging them not to do this because that's money was to bury my mother and he yelled again let then he took the gun and held it to my 4 year old daughters head and said he would shoot her if I didn't let go. So I let it go and they shoved my daughter and I into my dad room where my dad was in his wheelchair and my uncle shocked puzzled not moving was and the two guys who were family friends was there the two robbers then grabbed those two guys and ran out the house with then with the money I called the police at 7:47pm and the came out but did not chase after them they took statements and also  called the detective which my father and I have to prove that we have $12,000 cash in the house and called the guy who bought the house which he verified as well...
