A 22-year-old man who authorities say fatally shot his parents in their Long Prairie, Minn., home may have fled to Mexico, according to criminal charges filed Friday.

Dylan Bennett, who has no criminal record, was charged in Todd County District Court with two counts of second-degree murder in the deaths of Barry Bennett, 63, a former NFL player and Long Prairie physical education teacher, and his wife, Carol, 66.

The two were found dead Wednesday in their home after a friend became concerned when phone calls and texts to the couple had gone unanswered since Tuesday. Barry Bennett was last seen alive about noon on Monday while he was in town, according to investigators.

Last December, Barry Bennett reported to the Todd County Sheriff's Office that Dylan, who had been in a mental health treatment facility, had expressed thoughts about killing his parents.

According to the criminal complaint, Barry Bennett was found dead in the home's entryway. He had been shot multiple times. His wife, who also was shot multiple times, was found on the kitchen floor. The autopsy and investigation indicated the couple were shot sometime Monday.

A vehicle used by their son was still at the home, the complaint said. On the car seat was an empty box for a 9-millimeter handgun, loose 9mm rounds and another box of 9mm ammunition. A car used by Carol Bennett was missing.

Authorities said Dylan Bennett withdrew a large sum of cash from the couple's bank account about 9 a.m. Monday. The complaint said it is likely he made his way to Columbus, Ohio, where he boarded a flight Wednesday to Atlanta and then to Cancun, Mexico. Phone usage indicates he was likely in Mexico as recently as Thursday, investigators said.

The court record also states that Carol Bennett's debit and credit cards were used at locations in Wisconsin, Illinois and Ohio on Monday, Tuesday and Wednesday. Before her son boarded his flight from Columbus, court records say, he met up with someone and asked that person to hold onto his gun. Carol Bennett's Hyundai was later found in a motel parking lot in the Columbus area.

Anyone with information on Dylan Bennett's whereabouts is asked to call the Todd County Sheriff's Office at 320-732-2157 or 911.
