Francisco Gutierrez, better known to us as "Captain Jack," has passed away this morning at the age of 43.
In 2002 Captain Jack was diagnosed with a stroke. Though his lifestyle heightened the chances of another stroke, he continued to live life doing what he loved. He collapsed on Monday at a party in Spain, fell into a coma, and was pronounced dead today. He is survived by his ex-wife and son Francisco (21).
There's no point in masking the fact that we're connected to Captain Jack through his music on DDR. All of us have heard it; all of us have loved it. He's become about as much of a part of DDR as DDR itself, and thus the entire music game community is affected by this tragic death.

Palma de Mallorca: Francisco Guterrez aka "Captain Jack" ("Drill Instructor"

The drama around "Captain Jack" started at a party at Palma. The native-born Cuban (wearing his dance commander uniform) grasped at his chest and collapsed. Siegfried Blau, a good friend: "It was awful. We called the ambulance right away. But Franky wasn't transportable. He lay on the terrace for a hour, the paramedics battled for his life." Slightly stabilized he was finally transfered to the hospital.
Three years ago the singer suffered a crippling stroke. He had a hemiplegia, could barely speak. "Of late Franky had a lot stress, was traveling around, had a lot of gigs", said his manager Niebergall. And just now, where he met his son Francisco (21, lives at Miami) again after years on Mallorca, he was hit by a second stroke that caused his dead.
Niebergall: "Despite having high blood pressure since years, he didn't take his medication." His hits won't be forgotten...
