SATSUMA, Fla. -- This Friday, a vigil will be held for still missing Haleigh Cummings.

This year, the vigil will be held at the home of Annette Sykes, Haleigh's great grandmother.

The home is located at 302 Osceola Avenue, Satsuma.

The vigil is scheduled to take place at 6:30 p.m.

Friday marks three-and-a-half years since Haleigh disappeared.

Misty Croslin, the now ex-wife of Haleigh's father, Ronald Cummings, was the last person to have seen Haleigh prior to her disappearance. Croslin claims to have gone to sleep that night and when she awoke, Haleigh was gone.

Both Croslin and Haleigh's father Ronald are currently serving prison time for drug trafficking charges. The two were sentenced in early 2011 after undercover investigators made several illegal prescription drug purchases.

Investigators with the Putnam County Sheriff's Office have announced publicly they believe Haleigh is dead, but her family still remains hopeful she will be found alive.

The reward for information leading to Haleigh Cummings' whereabouts is $30,000.

If you have any information regarding the case you are asked to call Crime Stoppers at 1-866-277-TIPS.
