A Staten Island mom was stabbed to death outside the NYCHA building where she lived during a wild brawl involving about 20 women — and her 12-year-old daughter, cops and neighbors said Wednesday.

The Pitt men claimed victories of 210.5-89.5 over GW and 227-70 over its backyard brawl rival West Virginia. The women were similarly victorious, 215.5-84.5 over GW and 240-57 over the Mountaineers.
