Dover Police investigators worked with two police departments in Pennsylvania to arrest a Pa. couple Wednesday morning and charged them with the murder Monday night of Michael Gklotsos, who was the owner of Hollywood Diner in Dover.

Dover Police detectives charged a Pa. couple Wednesday morning with the murder of Michael Gklotsos as well as home invasion, robbery, kidnapping and related offenses.

A crucial photo provided to Dover Police helped investigators move swiftly to zero in on the two suspects, Dover Police Lt. Daniel McKeown said.

Detectives were able to identify the driver depicted in the photo taken from surveillance video that was released to the media as a person of interest in the murder, McKeown said. The public provided numerous possible suspects, which led to police identifying the driver as Joshua Lemonick, 20, of Newtown, Pa.

McKeown declined to disclose where the video image came from.

"I'd rather not release that as it may have a negative effect on the provider," he said.

The investigation also revealed that Lemonick's girlfriend, Angeline Terek, 23, of Bristol Township, Pa., had ties to the Dover area and knew the victim, McKeown said. Continued investigation led to detectives obtaining an arrest warrant for both suspects.

"We believe robbery was the motive and his business ownership was most likely a factor but can't say for sure," McKeown said.

Dover Police Department worked in conjunction with Newtown (Pa.) Township Police, who apprehended Lemonick at his residence on Cambridge Lane in Newtown at approximately 7:30 a.m. Wednesday, McKeown said.

Dover Police Detectives then contacted Falls Township, Pa. Police after receiving information that Terek may be in the area, he said. Falls Township PD arrested her at approximately 11 a.m. walking in the area of the 200 block of S. Olds Blvd.

Both suspects will be held in Pennsylvania pending extradition hearings, police said. The investigation continues but it appears that robbery was the motive for the crime.

Gklotsos was murdered at approximately 10:30 p.m. Monday, police said. At 10:42 p.m. Monday, Dover Police responded to a female caller who reported that she had been abducted from a residence in the 100 block of Acorn Lane and was released unharmed.

The woman told police that a man at the residence was assaulted during what she reported to be a home invasion. Dover Police Patrol Officers responded to the address in the 100 block of Acorn lane and discovered Gklotsos, 59 ,dead inside the residence.

The Delaware Medical Examiner's Office determined that Gklotsos had been strangled.

Anyone with information about the incident is asked to contact the Dover Police Department at (302) 736-7111.
