MOON TOWNSHIP, Pa. — Investigators are still trying to figure out what caused a Moon Township home to explode earlier this month.
Officials said the explosion trapped the 47-year-old homeowner, Shawn Landa, who remains at UPMC Mercy Hospital.
Hospital officials said Landa’s condition continues to improve daily.
Neighbors found Landa buried in the rubble after the blast about 6:45 p.m. on Oct. 12.
Some of that glass hit Alan Lisica, 61, who lived next door to Landa. Lisica was released from the hospital on Tuesday.
Columbia Gas officials have said they found no natural gas leaks outside Landa's home, but investigators haven't ruled out a leak inside the house or problems with gas appliances as possible causes.
