Terrorism vs. suicide vs. insanity in Ozone Park explosion

From DNA Info:

A man apparently making low-grade pipe bombs with powder from fireworks blew himself up inside his Queens home Monday morning, sources said.

Theodore Ellinghaus, 50, ignited the blast on 111th Avenue in Ozone Park just before 9:30 a.m. and the explosion blew him apart, a source said. He was dead by the time paramedics arrived.

Investigators are looking into whether he was building bombs as part of a dispute with a former employer, a construction company. A police source described Ellinghaus as an "emotionally disturbed person."

From the NY Post:

A Queens man was killed after a powerful firecracker exploded in his home this morning, and law-enforcement sources said cops are looking into whether he may have committed suicide with it.

The 50-year-old man was clutching the M80 near his waist in the hallway of his Ozone Park home when it went off at 9:28 a.m., police said.

The explosion ripped off two fingers from his hand and tore a hole through his stomach, leaving his organs exposed, sources said.

Horrified relatives, who were at the 111th Avenue house at the time of the incident, made the grisly discovery.

Police are investigating whether the victim, who recently told neighbors he was suffering from depression, had decided to kill himself with the firecracker.
