Court records say a Greeley man gunned down in front of his home last week may have been killed for his $110,000 life insurance policy, payable to his ex-wife.

Two men, Cecil Erb and Justin Brunner, both 27, have been arrested in the death of Jeffrey Watson Sr., 44. Investigators say Erb is the boyfriend of Watson's ex-wife, Georgia Watson.

Court records show Georgia Watson is the sole beneficiary of the $110,000 insurance policy.

Georgia Watson hasn't been arrested, and she denies any involvement in the slaying. Court records do not say she had knowledge of the alleged plot to kill her ex-husband.

Jeffrey Watson was shot in his pickup early Thursday as he prepared to leave for work.

Authorities allege Erb was the shooter and Brunner helped plan the crime.

Police in Dubuque, Iowa, arrested Erb on Friday on a first-degree murder warrant issued in Greeley. He is being held without bond in the Dubuque County jail. Authorities say they plan to begin extradition procedures to bring him back to Colorado.

Greeley police arrested Brunner on Saturday on suspicion of attempted first-degree murder and conspiracy to commit first-degree murder. Brunner is being held in the Weld County Jail on $1 million bond.
