Jack Elijah Turner

The search for Jack Elijah Turner, which led police to northeastern Mercer County earlier this week after a double murder in Crawford County, has now shifted to Florida.

The St. Johns County Sheriff's Office in Florida alerted the community on social media Tuesday night, asking for information on the whereabouts of Turner. Turner lived in the St. Augustine area prior to moving to Pennsylvania, according to the St. Johns County Sheriff's Office.

However, the sheriff's office now believes Turner, who is being sought for questioning in a double homicide in Crawford County, is no longer in that area.

The department tweeted the update around 10:30 this morning.

"The investigation into the whereabouts of Jack Elijah Turner have led investigators to believe he is no longer in St. Johns County. Sorry, we cannot share further on how or why they have made the determination."

On Facebook, the department had a longer message that contained this information:

"With that being said, history has shown us subjects sometimes double-back or change course at will, so we encourage everyone to stay aware of their surroundings (as you should always). Should anyone believe they observe Turner, notify the nearest local law enforcement responsible for the jurisdiction by calling 911."

As police in Florida were warning residents that Turner had been spotted in St. Johns County, police in Millcreek were filing charges against him for the hold-up of a Kwik Fill station in the township at approximately 5:30 a.m. Sunday.

Turner, 21, is being sought for questioning in the homicides of Shannon Whitman, 49, and Darrin Whitman, 10, his step-mother and half-brother, respectively. The mother and son were both killed by single gunshots to the head Saturday evening at their Route 198 home. Turner faces a felony charge of theft by unlawful taking for allegedly stealing a silver or gray colored Lincoln MKS from the site of the homicides.

Turner now also faces felony charges of robbery, possession of firearm prohibited and receiving stolen property and misdemeanor charges of theft by unlawful taking, terroristic threats and possession of weapon in the Kwik Fill robbery. The charges were filed by Millcreek Police Department through the office of Magisterial District Judge Laurie Mikielski.

A warning was posted on Facebook by the Stoneboro Borough Police Department Monday morning, advising residents to be cautious while Pennsylvania State Police searched for Turner.

Turner is believed to be armed and dangerous, according to Pennsylvania State Police. Anyone with information in the case should contact state police at Meadville at 814-332-6911.
