"On May 7 when Chris picked him up from Georgia, I said 'Chris make sure you take care of my dad up there' — then you do this?" Jackson said. Memphis Police say Collins also withdrew money from Finnie's bank account multiple times since he has been missing.  "That math ain't mathin' to me," Jackson said.  Understanding Peripheral Arterial Disease (PAD) The Importance of Blood Donation for Sickle Cell Patients Downtowners dodge for cover as shots fired on Front Street High school football scores, Friday, Sept. 20 Trump's shutdown push falls flat with Republicans As for who set the fire at Collins and Finnie's home, the Memphis Fire Department says the investigation continues.  Collins is due back in court on Monday.
