DENVER -- Bonfils Blood Center is asking people for donations after 58 people were killed and 515 were wounded in the deadliest mass shooting in U.S. history.
All blood types are needed from donors, but especially O-positive and O-negative.
Bonfils said it has met its needs for donations for the shooting victims after hundreds of people turned out at centers in Las Vegas and in the Denver metro area on Monday to help.
More than 700 people donated blood at Bonfils centers, double the amount for a typical Monday.
But blood has a shelf life and if it's not used right away, it can go bad.
Lone Tree is sponsoring a blood drive on Wednesday for the shooting victims. It will be held from 9 a.m. to 2 p.m. at 9220 Kimmer Drive.
Donors can schedule appointments online or by calling 303-363-2300. Donors can also walk in to any of Bonfils' eight donor centers in the Denver metro area.
Donors who are as young as 16 years old must have parental consent. All donors must weigh at least 110 pounds and be in general good health.
