Birmingham police are investigating the city's first two homicides of 2017.

The first shooting happened on New Year's Day, but the female victim died on Monday night, police said Tuesday. The second happened Tuesday morning at an eastern Birmingham apartment complex.

Birmingham police Sgt. Bryan Shelton identified the first victim as Christina Anderson. She was 30.

The Jefferson County Coroner's Office identified the Tuesday morning victim as Randale Lamar Oden. He was 34, and lived in Bessemer.

Shortly before 10 p.m. on Sunday, the city's North Precinct officers were dispatched to the 800 block of Center Street North on a report of someone being shot. When they arrived on the scene, they weren't able to find a victim but did see evidence of a shooting, Shelton said.

Their investigation led them to Princeton Baptist Medical Center, where they found a vehicle outside of the emergency room with blood inside. Hospital staff told police the victim had been shot and was being treated.

Anderson was then moved to UAB Hospital, where she was pronounced dead about 2:23 p.m. on Monday. Shelton said they do not know a motive in the slaying, and do not yet have any suspects. Authorities said it is believed Anderson was walking down the street with another person when she was shot.

"Preliminary investigation suggests that the victim possibly knew the shooter, but this is still an open investigation and other questions must be answered,'' he said.

The second homicide happened about 2 a.m. Tuesday at The Oaks apartments on Earline Circle. When police arrived on the scene, they found Oden just outside the front door of an apartment.

Detectives learned Oden and his ex-girlfriend got into an argument at another apartment in the complex. During the argument, the Oden assaulted his ex-girlfriend, said Lt. Sean Edwards.

Witnesses at the scene intervened by separating Oden and his ex-girlfriend. The ex-girlfriend proceeded to leave, but was followed by Oden to the other apartment. Once there, the ex-girlfriend knocks on the door of an acquaintance apartment and the acquaintance noticed Oden holding the ex-girlfriend in some type of choke-hold.

At that time, Edwards said, an argument started between both men which eventually led to the acquaintance shooting Oden. The acquaintance was detained and transported to police headquarters for further questioning.

There were 104 homicides in the city, of which 92 were deemed criminal by authorities. In all of Jefferson County, there were 151 homicides, up from 144.

Of the 104 homicides in Birmingham, 10 have been ruled justifiable and two were officer-involved shootings by outside law enforcement agencies - the Shelby County Sheriff's Office and the Irondale Police Department. Birmingham police do not count homicides ruled justifiable in their year-end tally because they only have to include criminal homicides in what they turn in to the FBI each year.

Here is a year-by-year look at homicides in the city for the past 25 years: 1991, 141; 1992, 140; 1993, 124: 1994, 135; 1995, 121; 1996, 113; 1997, 108; 1998, 85; 1999, 81; 2000, 89; 2001, 80; 2002, 71; 2003, 87; 2004, 64; 2005, 105; 2006, 109; 2007, 93; 2008, 88; 2009, 71; 2010, 62; 2011, 57; 2012, 72; 2013, 66; 2014, 59; 2015, 66 and 2016, 104.
