A woman from St. Charles who had not been seen alive in a week has been found dead, police said Tuesday. One person has been arrested, and charges are likely to be filed in her death.

The Maryland Heights Police Department’s Chief Bill Carson said that Jacquelyn “Jacque” Elizabeth Mitchell’s body was found in a 2200 block of Palestra Drive apartment. She turned 39.

Monday night, officials from St. Charles and Maryland Heights found out about it. Carson said it had been about six days since Mitchell died.

No reason for death was given.

Joseph Dejoie V, who is 49 years old, lives in the apartment on Palestra. He was caught Monday night.

The St. Charles County Prosecuting Attorney’s Office charged Dejoie with second-degree murder, tampering with physical evidence, and leaving a body behind. Dejoie is being held at the St. Louis County Justice Center on a bond that can only be paid in cash, which is $1 million.

Chief Carson said that Dejoie and Mitchell knew each other.

The last time Mitchell was seen was March 14. Her family said she went to Maggie O’Brien’s in Sunset Hills around 7 p.m. to get something to eat after work.

Thursday, March 16, her family told police in St. Charles that she was missing.

A nearby jewelry store in the same shopping plaza had surveillance video that showed Mitchell getting into her car alone in the parking lot just before 11:30 p.m. The video’s owner sent it to Jacque’s sister, who gave it to the police.

Carson said that Mitchell left Maggie O’Brien’s house and went to Dejoie’s apartment, where he got there just after midnight.

On the weekend, Mitchell’s cousin found her Nissan Sentra in an apartment complex off Schulte Hill Drive, near Interstate 270 and Page Avenue. This was a break in the case. But at the time, the police had no idea where Mitchell was.

Tiffany Mitchell, Jacquelyn’s sister, said that her phone last connected to a cell tower near Highway 364 and Bennington. This is what led them to search in that six-mile area in Maryland Heights.

Chief Carson said that investigators from Maryland Heights and St. Charles saw Dejoie driving Mitchell’s Nissan Sentra on surveillance video from a business. They knew who Dejoie was and were able to find his apartment on Palestra.

According to a probable cause statement from the Maryland Heights Police Department, Dejoie admitted to killing Mitchell. Police also claim Dejoie admitted to leaving Mitchell’s body in his apartment, and to wiping down both her body and car in order to conceal or eliminate evidence.

Police said Dejoie has prior arrests for felonious restraint, first-degree rape, first-degree burglary, and possession of drug paraphernalia.
