Commonly used investigative tools, such as checking phone and bank records, have not provided any clues in the case of a missing James Island woman, Charleston County Sheriff's Office Maj. Jim Brady said Wednesday.

There has been no sign of, or contact from, 47-year-old Angela Trent since she reportedly left her 947 Mikell Drive home about 6 p.m. Sunday. The gold Chrysler Town and Country van that she departed home in was found Tuesday morning a few blocks away, near Stiles Point Elementary School.

Thorough searches of the van, the school grounds and other areas near the school, turned up nothing to shed light on Trent's whereabouts, Brady said. No sign of struggle was found in the van or the grounds, he said.

Trent's family reported her missing on Monday and said that as she left home she'd threatened to harm herself.

Zack Trent, the missing woman's son, said Tuesday the family remains hopeful she'll be found soon and unharmed. He said he preferred not to discuss details of the case.

Brady said foul play is not suspected. He said investigators did not conduct a ground search Wednesday. As part of the probe, they have obtained and examined bank and phone records, as they would routinely do in any missing persons case.

The examinations provided no new clues, he added.

Trent is described as a white female, 5 feet 2 inches tall with brown hair and green eyes. She was last seen wearing blue jeans and a white shirt with green stripes, Brady said.

Anyone with information or knowledge of Trent's whereabouts is asked to contact the Sheriff's Office at 843-202-1700 or Crime Stoppers at 843-554-1111.
