FORT WORTH--Two suspects on the run have been captured in connection with the fatal stabbing of a 25-year-old Tarrant County man during a brawl in Rendon early last week, according to the sheriff's department.

William "Dalton" Rich, 26, was wanted on a murder charge in the death of Jeffrey Hathcock. Amber Danne Moore, 33, was wanted on a charge of tampering with physical evidence in the case.

The two were found in a motel on Benbrook Highway after 8 p.m. Monday by a U.S. Marshal's Task Force, according to the sheriff's office.

Sheriff's investigators booked the pair into the Tarrant County jail after working around the clock on the case, at times dedicating their entire Criminal Investigations Unit to it.

It was welcome news for Hathcock's fiance, who has endured a hellish week.

"It was just kind of a relief that they're off the streets and not hurting anybody else," said Hannah Power. "He was always looking after his brother, siblings and friends."

Indeed, Sheriff Bill Waybourn told WFAA that Hathcock had intervened after his brother got into a fight last week outside of the Hog Wild Bar in southern Tarrant County.

When deputies arrived, the fight had moved to the road about a block from the bar, according to a news release. Deputies found Hathcock dead at the intersection of Renwood and Briar Rose Lane.

Rich and Moore fled the scene, as did another man, Austin Hummel.

Hummel, 28, was arrested a couple of days later on a charge of tampering with physical evidence. He is being held at the Tarrant County jail with his bail set at $15,000.

Power is expecting the couple's son in March.

She said the thought of not having Jeffrey by her side because of a senseless murder is overwhelming.

"Confused, angry, upset. All of these emotions just run through me," said Power.

Rich had been facing charges of marijuana possession and unlawful possession of a firearm in Tarrant County, according to court records. He has previous convictions for misdemeanor assault, evading arrest, criminal trespassing, drug possession and burglary of a vehicle.

Moore has previous convictions for misdemeanor resisting arrest and deadly conduct, according to court records.

Hummel previously has been convicted of misdemeanor assault and driving while intoxicated.
