Post-Gazette.com – Pittsburgh police have increased patrols in Homewood and East Hills in response to the shootings at a backyard cookout in Wilkinsburg last week that killed five adults and an unborn child. Zone 5 Cmdr. Jason Lando said the move did not result from any specific threat involving those neighborhoods. “We’d much rather be prepared for any potential retaliations than hopeful that there won’t be any,” Cmdr. Lando said. “This is all just precautionary.” A 23-year-old man, Walli Hardy, was shot to death Monday on Wheeler Street in Homewood, but it was not known whether that killing was related to the Wilkinsburg slayings.
