Police made a second arrest and were tracking other suspects Monday in a double shooting that killed a 1-year-old, an attack that angered public officials amid a bloody holiday weekend in which gun violence wounded or killed a dozen people.

Cornell Harvey, 26, of the first block of Glenwood Road was charged with first- and second-degree murder and assault in the shooting death of 16-month-old Carter Scott; the child's father, Rashaw Scott, was also critically injured Friday. Police had arrested another suspect after a chase through the Cherry Hill area immediately following the shooting, but did not say what led them to Harvey.

Detectives were seeking at least one known suspect, and possibly more, said police spokesman Anthony Guglielmi, who also called further arrests "probable."

Investigators were meanwhile busied by a spate of incidents on a weekend that has often violently marked the start of a summer uptick in crime.

The incidents prompted Mayor Stephanie Rawlings-Blake and other city leaders to pledge a crackdown on repeat violent offenders, something that has long been a priority of top justice officials.

"This weekend was a sad reminder of the serious work ahead of us as a community to reduce crime and violence in Baltimore," Rawlings-Blake said in a statement. "We are going to continue to focus our efforts on repeat violent offenders and illegal guns while building trust with the community and increasing foot patrols and deployments in our neighborhoods. Reducing crime and violence remains the single most important priority of this administration."

City Councilman Brandon Scott said that Memorial Day weekend crime has come to be expected, whether or not the holiday brings heat, because people are out in larger numbers. He called the shooting of the toddler Carter in particular "unacceptable."

"You get angry any time someone is shot or is a victim of violence, but when it's a truly innocent child, it's very sad," Scott said. "To have that happen to a 1-year-old child, it's just unspeakable to me."

Police Commissioner Anthony W. Batts said in a statement Monday that the child's death "reaffirms the need and importance of communities working collaboratively with the BPD to help rid our communities of gang activity and gun violence."

Police described the toddler's shooting as an apparent accident connected to a targeted shooting of his father. The Scotts were shot Friday inside a parked red Chevrolet at the Cherrydale Apartments in Cherry Hill. According to police, three men wearing latex gloves, two in hooded sweat shirts, fired at least 16 shots as the father and son sat in the vehicle — Carter in the back passenger seat.

The child was found unresponsive with a gunshot wound to his leg and taken to Johns Hopkins Hospital, where he was pronounced dead about an hour after the shooting. Scott was in critical condition at Maryland Shock Trauma Center.

One suspect, 20-year-old Eddie Tarver of the 200 block of Cherry Hill Road, was arrested after a police chase on foot, by car and via police helicopter over six miles.

Harvey and Tarver are both being held at Central Booking.

The shooting was a violent start to the holiday weekend.

Saturday afternoon, a man was shot multiple times near West Cross and Carroll streets in Pigtown, after being approached by an unknown man who fled on foot. Police said concerned citizens soon identified the gunman.

That led officers to a few blocks away in the 400 block of S. Poppleton St. Police put out a description of the suspect, and officers — including one who had been key in Tarver's arrest the night before — attempted to arrest a man who matched the profile. The officer, who has not been named, shot the suspect multiple times.

A fatal shooting in the 4500 block of Marble Hill Road in Northeast Baltimore followed later that evening, and there was a spate of five non-fatal shootings Sunday.

Two incidents followed on Memorial Day. Police found a man with gunshot wounds to the arm and stomach in the 1600 block of 32nd Ave. early Monday, while a victim with gunshot wounds walked into Maryland Shock Trauma Center in the afternoon.

The violence was enough to surpass two recent Memorial Day holiday weekends. In 2012, police increased patrols for the weekend after eight people were shot on the Thursday night before the weekend. Two years earlier, nine people were shot over the same long weekend.

Councilman Scott called for a continued focus on tougher sentences for criminals wielding guns in the city — a small group that is responsible for much of the violence, he said.

"The people who get shot and shoot people are the same people over and over," Scott said.

According to court records, a Cornell Harvey with the same birth date and address released by police Monday was acquitted of the October 2010 murder of a 24-year-old woman. But court records charging Harvey in the Cherry Hill shooting list the 4100 block of Bright Road in Charlotte, N.C., as his address. Guglielmi said he could not explain the discrepancy Monday night.

Police said Scott, the toddler's father, also had a criminal record. Court records show a man of the same name and age was acquitted of homicide and gun charges in October.
