A second suspect has been arrested in connection with Friday's homicide in Chandler.

A second suspect has been arrested in connection with Friday's homicide in Chandler.

According to a probable cause affidavit, Keven Jimmy Ray Hallmark, 22, of Chandler, was arrested and remains jailed on a first-degree murder complaint in the Lincoln County jail.

The first arrest made in the case Friday was Dominique D. Gill, 22.

Both suspects remain jailed without possibility of bond; formal charges have not been filed.

Both are suspects in the homicide of Sam Brock, 41, from Odessa, Texas. He was found dead Friday in a room at the Lincoln Motel, located along Route 66 in Chandler.

According to affidavits in the case, Gill was arrested first after allegedly crashing the victim's pickup in Creek County. Hallmark was tracked down and arrested at an abandoned mobile him in Chandler, where investigators found him with bloodstains on his T-shirt and in possession of the victim's laptop, warrants show.

The investigation was launched when Brock's body was found face down with what appeared to be a fatal throat laceration, with a large fixed-blade knife found near the body.

Brock, who was a guest of the motel, had registered with a vehicle displaying a Texas license plate. When that Dodge pickup wasn't found parked at the motel, police entered it into a national crime database and began a search for that vehicle.

The Oklahoma Highway Patrol had discovered Brock's vehicle was in a crash Friday near Kellyville in Creek County. Troopers had Gill, the believed driver, in custody, after finding him walking down a road about one mile from the pickup.

During a search of Gill's person, troopers found items including hydrocodone and a set of keys to room No. 207 at the Lincoln Motel in Chandler, the paperwork shows.

Gill was transported to Chandler for further questioning about the homicide and it was discovered he was an occupant of Room No. 108 at the Lincoln Motel on Thursday. There, investigators found a bloody handprint on the entrance door, while a search of that room resulted in authorities finding two cell phones, with one of those belonging to the victim, the warrant reads.

When Gill was questioned Friday night, the warrant shows he claimed he rented a room and let an unknown male named "Jeremy" stay with him and that they shared a beer before he fell asleep.

"Gill said the next thing he remembers, he woke up in the woods near Tulsa and that he had a feeling he needed to run away," the affidavit reads, with Gill claming he didn't know how he came to be in possession of Gill's pickup.

Authorities noticed a small amount of blood on his coat sleeve, but Gill said the jacket wasn't his property, the document reads.

As investigators from Chandler police and the District 23 Drugs and Violent Crimes Task Force worked the case, they later interviewed two people staying in another room at the motel.

Those two witnesses reported having dinner with Brock about 6 p.m. Thursday and further identified Hallmark as one of two men who came to their room that night when one of them borrowed Hallmark's phone to make a call. The probe eventually led authorities to an abandoned mobile home where they encountered Hallmark.

"Investigators immediately saw large spots of what appeared to be dried blood on Hallmark's shirt," the warrant shows.

After he was taken into custody, a laptop computer, believed to belong to the murder victim, along with backpack, was found and seized.

Upon questioning, Hallmark allegedly told investigators that he had met Gill the night before and Gill invited him to stay in Room No. 108 with him.

Later in the night, "this guy" walked into his friend's room at the motel, Hallmark told authorities, adding that he and Gill confronted him.

"Hallmark said he asked the guy what he was doing and the guy told him he must have gotten the wrong room," the warrant reads, with Hallmark indicating the guy was drunk.

Hallmark said he put the guy in a headlock and Gill began kicking the man in the face and then he and Gill dragged the man into his room and went to wash his hands.

When he returned from doing that, Hallmark told investigators that Gill told him he had cut the man's throat.

"Hallmark said he stole a laptop off the table and left the room," it reads. A short time later, he heard tires squealing and assumed it was Gill stealing the man's truck.

According to the affidavit, when Hallmark was asked if his fingerprints would be on the knife, he said he initially picked it up to steal it, but that he put it down and then Gill picked it up and must have used it to cut the man's throat.

The entire case file will be reviewed by the district attorney's office for consideration of formal charges.
