I'm not too sure how many of Matt's family and friends and how often but its worth a try. I am the mother of his youngest. She (Kyra) was born August 21st, 2007. I didn't learn of his passing away until Kyra was about 2 weeks old. Well anyways my email is available with my name if anyone wants to contact me.
RIP Matthew Wade Sisco, you would've been a great father to that little girl.
