The Dec. 2 mass shooting at a San Bernardino medical center left 14 people dead, over 20 injured, and countless others without their friends and family

For many, time will be the only means of healing wounds. But there are ways in which you can help the victims, especially those who need a blood transfusion and remain in serious or critical condition.

Blood donations

The LifeStream blood bank is looking for Southern California residents to donate blood by visiting Ontario, Riverside, Victorville, and La Quinta locations, or through mobile drives. Those with O-negative blood are strongly encouraged to help. Appointments can be made through their LifeStream webpage.

American Red Cross centers across the southland, including some in Rancho Cucamonga and Riverside, are also accepting donors. Appointment can be scheduled online or through 1-800-RED-CROSS.

Fundraising websites

GoFundMe and YouCaring pages have been set up for those who lost their lives in last week's shootings. San Bernardino Mayor Carey Davis set up a page, but there is much more to be done for each individual's families.

One memorial fund is for Benneta Betbadal, a 69-year-old mother who leaves behind three children. Another is for the Wetzel family, made up of Renee Wetzel and her six children. Renee, a stay-at-home mom, lost her husband Michael during the massacre.
