ST. AUGUSTINE, Fla. – A 35-year-old man last seen Sunday at a wedding in St. Augustine has been reported missing, the St. Augustine Police Department said.

Police have asked for the community's help to find Donald Jackson, who was last seen at a wedding at the River House on Marine Street at 10:40 p.m. Sunday.

Jackson drives a 1999 black Isuzu Rodeo with Florida tag 7700IK and was believed to be driving from St. Augustine back home to Green Cove Springs when he disappeared.

Jackson was last heard from by phone as he was about to leave the wedding, but when his mother woke up the next morning, he was still not home. Attempts to contact Jackson by phone have been unsuccessful.

He also did not show up for work at Garber Auto Mall this week, leading his boss to go to Jackson's home to check on him.

The family immediately began calling area hospitals and filed a missing persons report with the St. Augustine Police Department.

Police said Jackson's cellphone last pinged a tower at about 5:30 a.m. March 7 in the area of State Road 16 and State Road 13, which would have been on his route home to Green Cove Springs.

Jackson's family stressed that he is not a drug user, is very reliable and always keeps in touch with family, so they are concerned that they have not heard from him for several days.

Anyone with information on Jackson's whereabouts is asked to contact the St. Augustine PD at 904-825-1070.
