abandon houses in detroit that area gangs called home. >> i am pleading to the mayor of detroit, that area needs to be cleaned up. it's nothing but a garbage pit. >> there are thousands of houses in detroit that are abandoned. that they live in. >> just knock them down? >> flatten them. >> in fact, in 2010, the detroit mayor started a project to do just that. the house where matt's body has been found was demolished. ihab masalmani was convicted of first degree murder, kidnapping and carjacking, and sentenced to life in prison without parole. robert taylor was also convicted of murder, and he was also serving a life sentence without parole. both have appealed their sentences. >> it took literally one second, one second to end matthew's life. and, in that one second, that has literally turned our family upside down.
