TUCSON (KGUN9-TV) - Tucson police need the public's assistance identifying anyone who may be responsible for shooting 46-year-old Patrol Sergeant Robert Carpenter early Sunday morning. 

Sgt. Carpenter, a nearly 12-year veteran of the Tucson Police Department, was shot in the head by an unknown person around 5:30 a.m. Sunday while responding to one of two 9-1-1 calls that came from a residence in the 4000 block of east Elmwood, according to Sgt. Maria Hawke with the Tucson Police Department. 
Hawke tells KGUN9 that Carpenter was in stable, but critical condition following surgery.

Tucson police responded to the 4000 block of east Elmwood Road at around 1:43 a.m. Sunday after police were advised that an audible alarm was coming from the residence, according Villasenor. A Hispanic man was seen in the yard of the residence. The man did not comply with demands from an officer. Instead, he fled from the scene on foot, according to Hawke.

Officers searched for the man for about an hour, but were not able to locate him, Hawke says. They concluded their investigation at around 4:15 a.m.

A second audible alarm went off at around 5:15 a.m. and Sgt. Carpenter responded to check the interior and perimeter of the home. Shortly after exiting the residence at around 5:30 a.m., officers heard a loud noise and Carpenter fell to the ground, according to Hawke.  

Police believe that multiple burglary attempts were made at the same residence within a few hours Sunday morning.  

Villasenor tells KGUN9 that the man originally seen fleeing on foot is being sought as a person of interest. He is said to be between 20 and 30-years-old, 5-foot-8-inches-tall and around 160 pounds with a shaved head. He was seen wearing blue jeans and a dark blue jersey with the numbers 43 in large red lettering that is outlined in white. 
Police believe the man may have arrived at the residence on a bicycle and may have been wearing a baseball-style hat, according to Hawke.
During the investigation, patrol personnel, the entire SWAT team, all available K-9 units and an air unit responded to assist in search efforts. All units were unable to locate anyone involved in the shooting incident. Search efforts concluded at around 1:00 p.m. Sunday, Hawke says.
Police urge anyone with information about the identity or whereabouts of anyone involved in Sunday's incident to call 9-1-1 or 88-Crime. A monetary reward is being offered via 88-Crime for information that leads to the arrest of individuals responsible for the shooting, Hawke says.
