I point out in my story on this today that it seems a bit odd that there have been three double-murders in Lowell this decade, and all three involved brothers being killed.

The Donovan brothers murder in 2002, the Lincoln Street killing of Moises Cotto and John Tejada in 2004, and now the murder of the Delgado brothers, Luis and Hector.

Luis, who most folks called Tony, was well-known downtown, and a face most folks who spend time there have probably seen.

Nick Petrakos, who owns the Shamrock, was crushed. He and Tony went way back because Tony used to work as a concierge at the the Doubletree, and would bring hotel guests over to the Shamrock for a bite to eat or a few drinks.

They were very close friends.

Tony and Hector both had kids, Tony's son is 11 or 12, Hector's son is about 2. Both were doting fathers.

I've heard nothing bad about either of these guys. Even Kathleen Marcin, president of the Downtown Lowell Neighborhood Association said Tony was a good guy that she never heard a bad thing about.

Hopefully investigators are making some progress. They were very very tight-lipped about the whole thing tonight.

I'll post updates as I hear about them, but I got very little from police sources tonight.
