Long Beach, Calif. ? The grim story of the calm, bald gunman who killed a checker and a little girl at a supermarket here grew more bizarre as police Friday revealed a startling discovery: The remains of two people found in the man’s condo a block from the store had been there more than a year.

The bodies of the unidentified pair so decomposed that even gender identification was daunting were lying on a bed in a back bedroom where a window overlooks the Top Valu Market where gunfire erupted Thursday.

Antonio Pineiro, 48, shot six people before an officer fatally wounded him, Long Beach police said.

Pineiro owned the small two-bedroom unit, in the building at 436 Cedar Ave., where police and residents say his elderly Cuban parents lived. Friendly and outgoing, in contrast to their son, neither has been seen by neighbors for more than a year.

“I asked him where they were,” said condo neighbor Paul Cook, who recalled Pineiro regularly carrying large laundry detergent boxes to the unit, sometimes three at a time. “He said they’d moved.”

It was unclear if they couple were Pineiro’s parents, or if they had died of natural causes or had been killed. Neighbors described his mother as crippled, saying it often took her 15 to 20 minutes to climb a short flight of stairs, her husband following to guard against a fall.

The two people Pineiro killed at the store lived in the downtown Long Beach neighborhood around the store. Barbara Ibasco, 8, lived on Cedar, a block from the gunman.

Marcella Perez, 38, who worked several jobs to get by, lived a half-mile from the store where she worked as a checker.
