The Ionia County Sheriff’s Office continues to learn more about the homicide-suicide that resulted in the death of Lisa and David Somers and seriously injured Lisa’s daughter Amedy Dewey.
The incident occurred on I-96 near Nash Highway in Iona County’s Boston Township Jan. 6.
Detectives were recently able to interview Dewey as she continues to recover from her injuries.
“Lisa Somers and Amedy Dewey had just returned to Michigan from a scheduled cruise vacation on Jan. 6 by flying from Florida into the Gerald R. Ford international Airport in Grand Rapids,” said Ionia County Sheriff Dale Miller. “David Somers had been booked to attend the cruise with them, however, he opted not to go the cruise the day before they were set to depart.”
According to the Ionia County Sheriff’s Office, the shooting came after an argument between David and Lisa where Lisa accused David of infidelity.
“(Lisa had) an argument with David over the phone and in text messages prior to (Lisa and Dewey) taking a connecting flight from Florida to Michigan after returning from their cruise,” Miller said. “When the party left the airport, David Somers had been driving the couple’s 2011 Chevrolet Equinox. By all known accounts, neither Lisa nor Dewey knew that there was a shotgun in the back of the car.”
The argument continued as David drove the girls on I-96 near Nash Highway in Boston Township.
“The argument continued and escalated, which then caused David to become angry and begin driving erratically on the freeway and travel at very excessive speeds for the road conditions,” Miller said. “This erratic driving had been reported by independent witnesses who contacted the Sheriff’s Office in the days after the incident.”
David’s anger continued and he suddenly brought the vehicle to a stop on the side of the road.
“David pulled off the roadway coming to stop before getting out of the vehicle and walking to the back of the car,” Miller said. “Lisa and Amedy both got out of the vehicle, when Amedy reported hearing her moth yell ‘He’s got a gun.’”
Dewey told detectives in the interview that she quickly got back into the vehicle and tried her best to lay across the seat and hide from David.
“She reported that she was trying to call 911 on her phone, but was unsuccessful before David Somers shot her. She reported looking back over her shoulder just before she was shot and that it took her a moment to realize what had happened to her,” said Miller. “The single shot was from a 12-gauge slug, which struck her in the face and head and caused very severe injury. Investigators had previously determined that the shot came form the back of the car through the opened lift gate. Amedy did not see or hear what happened to her mother.”
Dewey continued to tell detectives what was going through her mind at the time of the incident.
“Amedy told Ionia Sheriff’s Detectives that her immediate instinct was, ‘I’m not going to die. This is not how I’m going to die.’ Amedy described to detectives the steps she took to save her own life, including trying to use her cell phone to call for help, climbing over the front seat to use the horn and lights on the car and even getting out at one point to try and flag down passing motorists,” Miller said. “Witnesses calling 911 that evening reported seeing someone at the back of the car looking like they were trying to flag down cars. Nobody calling at that time knew the extent of the situation.”
It is unknown at this time if alcohol or narcotics contributed to the incident pending a toxicology report.
The investigation has also revealed that the Manistee County Sheriff’s Office, in fall 2016, had investigated David Somers’ relationship with a girl who was 17 years old at the time.
Police records show they interviewed the minor girl and Somers in August and September 2016 about alleged sexual contact between the two and also indicate that Somers had provided the girl alcohol on Aug. 30, 2016.
Court documents from 85th District Court show David Somers pleaded guilty Feb. 8, 2017 to a charge of furnishing alcohol to a minor. He paid a fine of $425 with no jail time or probation.
“Underlying domestic issues and accusations of infidelity were determined to be significant contributing factors,” said Miller.
The case remains open pending autopsy and toxicology reports in addition to other forensic testing before the case will be closed.
“Sheriff’s Detectives left their meeting with Amedy Dewey with a tremendous amount of respect for the courage, tenacity and strength that this young woman has displayed both during and after this ordeal as she continues to recover from this terrible incident,” Miller said.
