A Birmingham man was shot to death Saturday night, and police didn't have to look far for the suspect - he was sitting in the hospital lobby initially claiming to have found the wounded victim.

Birmingham police were dispatched to Princeton Baptist Medical Center about 10:15 p.m. Saturday after medical staff alerted them to a gunshot victim who had arrived by private vehicle. When officers got to the hospital, they learned 25-year-old Marvin Smith had died from his injuries, Birmingham police spokesman Lt. Sean Edwards said Sunday night.

Investigators learned the shooting happened in the 400 block of Third Street West, and were told the victim was taken to the hospital by a friend who was currently sitting in the hospital lobby. That friend, Edwards said, told detectives he arrived at Smith's apartment and found him outside on the ground bleeding from an apparent gunshot wound.

He then told police he and Smith were in dating relationship. At that point, he was taken to Birmingham Police Headquarters for further questioning. The friend later confessed to shooting the victim, Edwards said, and was put in the Birmingham City Jail on a 48-hour hold pending formal charges.

On Sunday, detectives obtained a formal murder warrant against 27-year-old Reginald Kennedy. He is being held in the Jefferson County Jail with bond set at $60,000.

Smith is Birmingham's 78th homicide this year and the second on Saturday, both of them domestic-related. Earlier in the day, 30-year-old Martha Bryant was found shot to death inside her Wylam home and her ex-boyfriend was found dead from an apparent self-inflicted gunshot wound in Fairfield.

Also on Saturday, 64-year-old Calvin Gunn was killed in his driveway when he and his wife returned to their Ensley home. Police believe Gunn was being robbed when he was shot to death. No suspects have been identified.

On Sunday, Birmingham recorded its 80th homicide when a shooting in the Kingston community left one person dead and two others injured. The shooting happened Ninth Avenue and 44th Place North. Birmingham police on the scene said the victims were outside, and the incident could have been a drive-by shooting.

One victim died at the hospital, one victim is in critical condition, and the other is in stable condition.

Of those 80 homicides in the city, at least six have been ruled justifiable and therefore aren't deemed criminal. Two others were officer-involved shootings by outside police agencies: The Shelby County Sheriff's Office and the Irondale Police Department.

Birmingham ended 2015 with 92 homicides, a 55 percent increase over 2014, making 2015 the city's deadliest year since 2008.

In all of Jefferson County, there have been 116 homicides this year. In 2015, there were 143 slayings countywide, up from 88 in 2014.

Anyone with information on any of the cases is asked to call Birmingham police homicide detectives at 205-254-1764 or Crime Stoppers at 205- 254-7777.
